What Has Changed Recently With Electricians?

Simple Electrical Troubleshooting Techniques to Learn If You’re An Electrician Being an electrician, you could only look forward to coming across with a wide variety of complicated electrical circuits and drivers which will later break down and malfunction. There is great chance that you will be an expert in repairing said devices. But while you are yet approaching for that time, it is recommended that you learn first the basic troubleshooting tips and techniques for such problems. Please proceed onto reading if you want to get started. Nowadays, the solid-state electronic AC motor drive has become really common inside industrial plants. It is in control of a wide range of devices like mixers, machine tools, chillers, air handlers, conveyors and pumps. 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. Because the rectifier section is most of the times the cause of such device failutres, it is necessary for you to develop understanding on diodes, transistors, silicone controlled rectifiers and insulated gate bipolar transistors. Talking of AC drives, the most popular used are the pulse width modulated inverter drives. What happens is that the AC line voltage is turned into a DC and then built again into a variable frequency. Change in frequency can cause changes in the motor speed. The motor torque is then maintained by keeping into constant ration the volts-to-frequency.

Now, how do you troubleshoot motor drives? 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. It takes a methodical approach to be able to effectively troubleshoot a variable frequency drive. The divide-and-conquer method that is taught in almost all technical schools become handy when your knowledge about the device to be repaired is not that much.

One thing you need to be mindful of is that a good troubleshooter will always decide to set aside first the box or section where signal is no longer passing and right after, gets the repair work started. 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.
