Questions About Repairs You Must Know the Answers To

Simple Electrical Troubleshooting Techniques to Learn If You’re An Electrician As an electrician, you are expected to encounter a lot of electrical circuits and drives that will malfunction when they age. There is great chance that you will be an expert in repairing said devices. But as you move onto the mastery level, it is best to gain knowledge on the basic techniques in troubleshooting those electrical devices. Just go on reading in order to started right away. In industrial plants, you will find the solid-state electronic AC motor drive widely used. It has the power to control different devices such as pumps, mixers, conveyors, machine tools, air handlers and chillers. Even more, it has the capability to controlling a large set of other electrical devices that were originally powered by DC or designed to run in a constant speed. As is usually the case, the said damages on electrical devices are caused by the rectifier section, so it makes sense for an electrician like you to develop understanding on transistors, insulated gate bipolar transistors, diodes, and silicone controlled rectifiers. The pulse width modulated inverter drives are among the most popular kinds of AC drives today. What it does is convert the AC line voltage into a DC inside the converter section and then reconstruct it to be a variable voltage output again. Changing of frequency usually results to a variation in the motor speed. For the sake of ensuring the motor torque is maintained, the volts-to-frequency ratio is put at a constant.

Now, what does it take for you to troubleshoot a motor drive? What makes this kind of problem much easier to settle and fix is the idea that most failures start and lie in the power sections and not in the circuit boards. Being an ordinary plant maintenance technician, it can be that challenging to gain expertise in the repair of circuit boards since there will not be so many problems on circuit boards to deal with. In order to successful fix a variable frequency drive, you need to make use of a methodical approach. If you know that you only possess limited knowledge about the device, then you put into use the method taught in many technical schools – divide-and-conquer.

You have to bear in mind that an excellent troubleshooter is one who sets aside first the section or box that is not passing then signal, and once done, begins on the work. It is even more necessary to remember that in the realm of troubleshooting a dead VFD quickly and effectively, you have to think of safety ahead of time. Even when capacitors are unplugged, they can retain dangerous charge that are harmful.
