Electrical Engineering Technician & Electrical Engineers
Though there are differences between electrical engineering technicians and electrical engineers, the two go hand in hand in most industries. Both technicians and engineers have a valuable and reliable skill set which allows for them to work in some of the world’s most demanding professional’s environments. However, it can be difficult when hiring a firm or choosing a career path to know the specific details which separate these two professions.
Here is a brief and straight-forward comparison between the job description of an electrical engineering technician and that of an electrical engineer;
An electrical engineering technician could be responsible for such tasks as:
- Assembling electronic and electrical programs, systems and prototypes using a variety of hand tools and basic measuring instruments.
- Installing and maintaining electrical control systems and industrial equipment.
- Troubleshoot, repair or modify prototypes, systems and programs in order to fix any existing or potential deviations.
- Set up and utilize test equipment
- Work together with electrical engineers and designers to predict, solve and avoid any manufacturing delays or potential problems.
- Prepare cost evaluations, set up schedules and project estimations.
Whereas an electrical engineer is most likely a supervisor or designer working at an electrical engineering consulting firm like http://www.brownengineers.net and is held accountable for major responsibilities including:
- Designing and implementing new electrical equipment, instruments, facilities or components and working together with an electrical engineering technician to develop and distribute operation manuals and maintenance requirements.
- Oversee a projects progress, cost and turnaround time, as well as assessing the budget and availability of additional materials or employees.
- Prepare and review technical drawings and assist an electrical engineering technician with interpretation, implementation and any potential or additional design adjustments.
- Compare and assess the equipment, components or programs used by competitors and adjust a project accordingly
- Receive and remedy customer complaints.
- Study and compile data from multiple sources including maps, land surveys, residential development, population or past projects to ensure top quality and project suitability.
- Train and hire project team members including electrical engineering technicians, technical illustrators and skilled trade workers.
Do You Know How To Use Electric Fuses?
An electric fuse is a current interrupting device that protects an electrical circuit. It is mounted within the circuit and is activated when excess current, which could damage the circuit, enters the circuit.
Fuses are used generally as a conduit between an electrical power source, and an electrical component arranged in an electrical circuit. They are designed for one time use only, hence, once it shuts down a device, it must be replaced.
Electrical fuses are part of the electrical systems in cars, trucks, motorcycles, boats and other type of vehicles. They function to stop the flow of electricity to a certain component of the system by making an open circuit, arising from an unsafe electrical condition.
There are three basic types of fuses. These are the slow blow, the fast acting fuses and the very fast acting fuses. The other terms for slow blow are time lag and time delay fuses or the TL for time delay fuses.
A major type of time delay fuse is the dual-element. It consists of a short circuit strip, spring connection and soldered joint. During current overload, the soldered joints get hot and start to melt. Then the spring shears the junction loose.
During short circuit, the short circuit element works to open the circuit. The slow-blow electric fuse allows a temporary and harmless rush of current to move into the circuit without breaking open. Rather it opens on the sustained overloads and short circuits. Slow-blow fuses are ideal for circuits with a transient surge of power. This lets current to continue flowing into the circuit at close to the fuse rating. This prevents the fuse from breaking open and having to be replaced. Usually, they are rated between 125% and 150% of the circuits’ full load amperes.
If you are looking for fuses for home use, the TL fuses are the best choice. Not only are they medium duty; but they are the recommended fuses for home uses. The TL fuses uses an Edison base, while the SL fuses uses a Rejection base.
The fast acting fuses are also called S and T fuses. They are heavy duty time delay fuses used for circuits that have critical or high motor loads. An S or T electrical fuse is also used for circuits that have motors which cycle on and off more often like the sump pump. It features longer time delay than the TL fuse. The difference between S and T fuses are their bases. The T fuse uses an Edison base, while the S fuse uses a Rejection base.
The very fast acting fuses are also called mini breakers. They are able to convert a fuse to a circuit breaker. A mini breaker electric fuse is a retrofit circuit breaker fuse that screws into an Edison base fuse socket. It is excellent as it converts a fuse into a push-button circuit breaker.
The mini breaker electric fuse has a little push button which pops out. Whenever the circuit is overloaded, you just need to reset the fuse by pushing a button. These types of fuses are designed to meet your needs.

Which Is Safer: The Electric Space Heater or Electric Fireplace?
According to the National Fire Protection Assoc. (NFPA) heating equipment was the second leading cause of home fires and home fire deaths.
The heating equipment category includes central heating, fixed and portable space heaters and wood stoves. Of these, fixed space heaters (wall mounted or freestanding propane heaters) accounted for 17% of the fires and 28% of the civilian deaths.
Portable heaters (propane and electric) caused far fewer fires, only 8% of the total, but accounted for 46% of the total deaths resulting from heating equipment fires.
So how can this be with increasingly stringent space heater manufacturing safety standards?
The best answer to this question comes from Fire Chief Eric Chichester of Parkersburg, WV, a state which had 6 space heater related deaths in October: “The problem isn’t really with the space heater itself, but with misusing it and leaving it unattended.”
If misuse of the space heater and not the space heater itself is the cause of fires, which type of heater would be prone to misuse more frequently; an electric fireplace or space heater?
Although far fewer electric fireplaces are sold in North America than small space heaters, close tracking of the occurrences of space heater fires so far this season has yet to reveal an instance where an electric fireplace was a contributing factor.
This suggests that people are less likely to misuse an electric fireplace and therefore the electric fireplace is safer. But this begs the question; why are electric fireplaces misused less than ordinary space heaters?
The answer to this lies in the overall size and design of the electric fireplace. The placement of the electric firebox in the middle of a 4 foot wide unit creates a natural buffer zone on either side between it and draperies, furniture or bedding that might be in the room.
By keeping flammables away from the heater you will practically eliminate the number one cause of space heater fires.
An electric fireplace is also regarded as a beautiful piece of furniture which makes it less likely that bags of clothing, boxes, etc. would be piled in front of it – never mind blocking the heat source.
The perception that an electric fireplace, by virtue of its size, is more powerful than it really is probably tempts fewer people to plug it into an overloaded extension cord. Plugging an electric fireplace into its own wall socket all but eliminates another potential fire hazard.
Finally, the flame display, crackling fire sound effect, and humming of the blower serve as a constant reminder the fireplace is running and makes it less likely it would be left on when the house is unoccupied.
Rather than trying to pit the electric fireplace against the electric space heater, the real purpose of this article is to remind everyone that any space heater can be a safe space heater if you keep it at least 3’ away from combustibles, don’t use an extension cord, and remember to turn it off when you go to bed and leave the house.
Get The Cheapest Bills From Your Business Electricity Provider
Naturally, the cost for power continues to rise each year. That may be the best if only one reason to take advantage of DIY electricity creating methods. Besides the fact that electricity is more and more cost prohibitive, that a major circuit may cease working at any moment for over consumption and submerge your town in boundlessgrey-outs, and the social imperative that our nation must convert to greener remedies for the preservation of the entire earth, we all should endeavor toward the option to convert to eco-friendly, the alternative electricity also know as off grid electricity.
What about Gas Generators?
Note: I would not even consider buying a natural gas electricity generator. It has been done, it doesn’t save any money, it’s a source of noise pollution, and its upkeep will cut a big piece of your financial resources. So you’d be better off to reconsider that idea.
The Alternative
Right on time, there is an excellent substitute to that: and that is home made source of electricity. You may have something about solar generated electricity and wind farm generated electricity. By the way, are you aware that your electricity corporation will even pay you for putting in DIY electricity equipment? Also, you canfind out how to build a solar panel yourself. In doing so, you can create energy yourself!
Not As Hard As It Sounds!
Its not that hard to generate electricity at home. Naturally, you may have tospenda large amount of effort in the research of how to complete that. Take some time to learn about your alternative power, and get familiar with vocabulary like: solar cells, wind generator, electricity inverter, solar power , wind turbine blades, PV panel, etc.
What about the price?
Amazingly enough, you can establish your own energy module with a minimum of material, and have your own renewable energy, save some dough on excessive energy bills, create your own power, even prompt admiration from people you know, and save a chunk on your electricity bill, naturally.
In Concluding
You owe it to yourself: Save cash on your bill, save the earth, and get a respectable return on your venture quickly. Start deliberating earnestly about changing over your inefficient corporate electricity source and replace it with a safe and sound, green, independent electricity setup. If you want to save some dough, just go deregulated.
Industrial Electrical Supplies
Several branches of technology and engineering are available for industrial application. In automation, industrial architecture, industrial design, industrial process, industrial arts and industrial applicability, there will be a need for products to support continuing development and manufacturing of products and services.
Products of the industry may be identified among chemical industry, petroleum industry, automotive industry, meatpacking industry, hospitality industry, food industry, fish industry, software industry, paper industry, entertainment industry, semiconductor industry, cultural industry, poverty industry.
Primary sectors of the industry are agriculture, mining, and raw material extraction. The secondary sector of the industry is manufacturing. The tertiary sector of the industry is in service production. Sometimes, there is a quaternary sector of the industry pertaining to intellectual services like research and development.
All sectors of the industry use electrical power in order to operate office equipment and industrial machinery. Electricity also provides sufficient energy for commercial lighting, cooking, and industrial processes. Because of the vast demand for electricity across all industries, it is viewed as a public utility infrastructure.
The four processes of the electrical power industry are power station, electric power transmission, electricity distribution and electricity retailing. These are geared towards electricity generation. The entire electrical power industry is heavily regulated because it is a natural monopoly wherein basically every member of the population demands it.
Industrial electrical supplies refer to all products and accessories that require electricity to operate and are used across all industries. Majorly, industrial electrical products include all fittings, wire, circuit breakers, safety switches, fuses, contactors and starters, lamps, and more. Other offerings include motors, lighting, material handling, fasteners, plumbing products, tools, and safety supplies. Companies marketing such supplies generally take out revenue on a business to business rather than a business to consumer relationship.
Companies providing industrial electrical supplies are built to provide efficient solutions for industries especially responding to the demand of electric motors. With the extremely flexible form of energy, electricity has been adapted to huge and growing number of uses. One best example industrial electricity’s use is in the telecommunications industry which has enabled communications around the globe in seconds.
Electrical Courses: What You Should Know
Our lives today are unimaginable without electricity and electricians are the people who bring electricity to our homes and offices. Earlier, the job of an electrician was considered a job of an artist and hence, no formal training existed. Knowledge was passed on from senior electricians to juniors. But, now the times are changing. Technology is advancing at such a rapid pace that any electrician who does not keep pace with technology will soon be pushed behind by better informed adversaries. Also, a formal training can lead to easier acceptance and immediate recognition in the market place. This brings up the need for electrical courses.
Electrical courses can address a variety of issues based on the target audience and since the audience is from varied cross-sections of the society, so are the courses. The education market is flooded with electrical courses, and a number of institutes have suddenly popped out, offering electrical courses. Some courses are meant for fresh people who wish to make a sound career as an electrician. These courses generally deal with all the basic knowledge an electrician would need as well as take the students through advanced modules to inculcate the intricacies of the profession in them such as safety at work, better installations, team management, working with futuristic materials and latest technology, etc.
Specialized electrical training to handle the installation and maintenance of electrical fittings at offices and factories are also available. Electricians tending to the needs of such commercial establishments have to be very professional and be able to work with large scale installations and ensure that these lines never fail as a single failure can result in a major financial loss, and sometimes even the life of the workers may be at stake. For large scale industries, electricians may have to work in teams and good electrical courses must address this issue also. Electrical courses incorporating a good amount of team work and extensive documentation in standardized codes of the profession are most suitable for such would-be electricians.
There are also electrical courses for those who wish to just learn a bit of stuff for their personal awareness and for handling minor jobs and emergencies. These courses simply consist of introduction to various aspects of electrical fittings and a few hands-on sessions to familiarize the students with the electrical stuff. And that is not all, some electrical courses are especially designed for people who have already been in the profession for quite some time and would like to prove their competence in a standardized format. Upon successful completion of these special electrical courses, experienced electricians can obtain a certificate, which they may need for a job in any big company. Also, certain institutes help in securing excellent jobs after completing the electrical courses they offer.
Hence, whatever you may want to learn to be a successful electrician, chances are very good that you will find a tailor made electrical course which can give you a jumpstart in your career as an electrician or boost your already booming career.
Why Not Start an Electrical Training Course
Electricians are indispensible in the modern world we live in. Any activities we may wish to do require electricity in one form or the other and each time we do any such activity, an electrician is involved in some way. Electricians have got their due only recently as earlier it was considered a mundane job. Now, it is a field as lucrative as engineering or medicine. As a result, a number of institutions offering an electrical training course have emerged in the past few years. These institutions aim to quench the thirst of the current society, thirsty for skilled electricians.
An electrical training course not only aims at supplying skilled electricians but also intelligent electricians. With the energy crisis growing at an alarming rate, the world is in need of intelligent electricians who would work towards the right implementation of designed installations. It is well known that transmission losses and other losses which can be accounted to poor electrical installations are capable of burning a wide hole in everyone’s pocket. With the need to conserve energy and hence electricity, the requirement of good electricians has increased greatly. This is where a good electrical training course can make all the difference by teaching the future electricians the need of the hour.
Another important aspect of the job of an electrician is emphasis on safety at work. Electricians are exposed to hazardous working conditions and even small mistakes can prove fatal causing loss of life. Every electrical training course lays great emphasis on such safety issues and a trained electrician is less prone to such mistakes than an untrained electrician. Basically, an electrical training course instils good working practices in candidates and prepares them to follow a safer modus operandi.
Apart from the two above mentioned critical issues, a good electrical course must also address the issues regarding technological advancements. A number of electricians are not as well acquainted with latest technology as we would like them to be. After going through a good electrical course, the importance of being abreast with the latest technology is understood by electricians and this helps them function better. Also, a number of other work place improvement methods are taught to would be electricians so that they do not repeat any mistakes of their predecessors.
The advantage of taking up a good electrical course does not end here. A good electrical course will also teach its candidates, tricks like the art of negotiating, managing customers, working towards better customer satisfaction, networking, and dealing with dealers, etc. Although no electrical training course can actually teach certain aspects of the career which experience can but, none the less a good electrical course sets you apart from the crowd. In today’s cut throat competition, one cannot even dream of not taking advantage of any opportunity at hand and an electrical training course is the advantage one can have over electricians having only the certification of experience. Experience will definitely come with time but a good certification will not and that is precisely why anyone should opt for an electrical training course while they can. As the saying goes, make hay while the sun shines.
A Start-Up Aims at Power Conversion to Save Electricity
A Southern California start-up backed by Google and prominent venture capital firms announced on Wednesday a technology it claimed could slash the electricity consumption of a wide range of devices like industrial motors, hybrid cars, computers and cellphones.
The result could be electric cars that drive farther without recharging, the disappearance of bricklike device chargers and solar panels that generate more electricity, according to the founders of Transphorm.
The company, based in Goleta, Calif., has developed a power conversion module that it says cuts energy waste by 90 percent. Currently, about 10 percent of the energy generated in the United States is lost as electricity because it is converted from alternating current to direct current and back, according to Umesh Mishra, Transphorm’s chief executive.
“That converts to hundreds of terawatts of energy loss,” said Mr. Mishra, a professor of electric and computer engineering at the University of California, Santa Barbara, during Transphorm’s unveiling at the Mountain View, Calif., offices of Google Ventures, the search giant’s investment arm. “We will save hundreds of terawatt hours when Transphorm’s technology is fully implemented, the equivalent of taking the West Coast off the grid.”
The four-year-old start-up has raised $38 million in funding from Google Ventures, Kleiner Perkins Caufield & Byers, Foundation Capital and Lux Capital to develop a new type of power conversion module based on gallium nitride, a compound used in LEDs. Google has yet to test Transphorm’s power module as the product hasn’t been available.
“The opportunity is to take 300 coal plants off grid effectively, said Randy Komisar, a partner at Kleiner Perkins.
Mr. Mishra said Transphorm had signed up customers like Yaskawa Electric Corporation, a Japanese maker of motors and industrial robots, and would introduce its first products in March.
Current conversion modules are based on silicon, a material that Mr. Mishra said was “running out of steam” in its ability to more efficiently convert power at high voltages.
He compared silicon-based power conversion modules to a dimmer switch that stayed warm even as it lowered the lights. A gallium nitride power conversion module is akin to a standard light switch that completely cuts the flow of electricity when turned off.
“Gallium nitride allows you to do that conversion without wasting energy,” said Mr. Mishra. “It can hold maximize voltage when off and minimizes loss.”
Gallium nitride is not a natural compound, and the challenge Transphorm faced was growing gallium nitride crystals that would survive transformation into power conversion materials and devices, according to Mr. Mishra.
Transphorm initially plans to single out the data center market, selling its modules to the makers of power supplies for computer servers. The potential to sharply reduce the electricity consumption of data centers attracted the interest of Google.
“With a global network of data centers, we understand the problem of waste heat,” said Bill Maris, managing partner at Google Ventures. “The bottom line is that waste is not good for shareholders, it’s not good for data centers, it’s not good for the equipment and it’s not good for the world.”
Mr. Komisar said another potential big market for Transphorm was inverters used to convert voltage in photovoltaic panels. By making inverters more efficient, solar panels can generate more electricity.
“We can take the power coming from the roof and make it more efficient coming back into the house at the inverter,” he said, noting that such a solution would be far less expensive than developing more efficient photovoltaic cells.
Gas and Electricity in Ovens – Which is Better?
There are more than two separate camps of cooks in the debate of gas versus electricity ovens. Some die-hard stalwarts, including many professional chefs, will insist that unless you’re cooking with gas then you’re not really cooking at all. Others swear by the reliability of cooking with an electric oven, whilst many cooks prefer to mix and match options with gas hobs and electric ovens.
With gas and electricity, it really comes down to a matter of personal preference and cooking style, but there are some general tips that can be observed to save you money on your utility bills whilst cooking.
One of the general principles of gas and electricity when it comes to ovens is that gas ovens are more expensive to buy but cheaper to run. Electric ovens, on the other hand, are cheaper to buy but more expensive to run. If you are investing a significant amount of money into an oven which is a long-term purchase rather than a quick fix, then it will probably work out cheaper over time to buy a quality gas oven rather than an electric one. Gas and electricity prices will invariably fluctuate but if electricity prices rise then gas prices tend to increase in tandem, and gas is usually cheaper than electricity as a rule.
There are a number of factors that can make different ovens cheaper to run though. Fan-assisted ovens, for example, increase the temperature inside the oven and spread the heat more evenly, allowing for a smoother cooking process. As extra heat is generated, fan-assisted ovens can cook at lower temperatures, thereby using less gas and electricity. Not only do fan-assisted ovens cook more thoroughly, they also cook more quickly, making them more fuel efficient and time effective.
Most ovens these days are electric, and what sets them apart from gas ovens is that they are cheaper to buy, tend to be more reliable, and can be more versatile. Modern electric ovens come with a host of additional functions including thermal grilling, defrosting, batch baking, and timers that can be programmed. Gas ovens tend to be more traditional but ultimately give cooks more control with their oven temperature.
In terms of oven hobs, gas is almost universally accepted as better for cooking, whereas electric is almost universally accepted as being better for cleaning purposes. Ultimately, whether you decide to go for straight gas, straight electric or a mixture of gas and electric, the oven you require will depend on the type of cook you are. For a solid all-rounder though, a fan-assisted electric oven with gas hobs is an excellent mix of gas and electricity, which is both versatile to use and reasonably cheap to run.
