How I Became An Expert on Electricians

Basic Electrical Troubleshooting Techniques Every Electrician Must Know As an electrician, you are expected to encounter a lot of electrical circuits and drives that will malfunction when they age. Sooner or later, you will be an expert in fixing the said devices. But now that you are yet a starter, it is an ideal thing to know of some practical measures to solve those problems. Kindly read on to get started. 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. It may also control all other device that are used to be powered by DC. Since the damages of such electrical devices are usually due to the rectifier section, it would help much to have knowledge on insulated gate bipolar transistors, silicone controlled rectifiers, diodes and transistators. When it turns to AC drives, the most commonly utilized are the pulse width modulated inverter drives. It functions by converting the AC line voltage into a DC and then constructed again to become a variable frequency as well as a variable voltage output. Change in frequency can cause changes in the motor speed. For the sake of ensuring the motor torque is maintained, the volts-to-frequency ratio is put at a constant.
A 10-Point Plan for Services (Without Being Overwhelmed)
Now, what do you need to do in order to fix a problematic motor drive? Most of the times, problem like this is not so hard to repair because most problems are within the power sections and not in the circuit boards. If you are a plant maintenance technician, you are not likely to experience a great number of problematic instances that have something to do with the circuit boards, which is the reason why mastering such may be difficult. A methodical approach has to be utilized in order to effectively and successful repair a troubled variable frequency drive or VFD. 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.
Getting Down To Basics with Repairs
Always keep in mind that a good troubleshooter isolates the section that is not passing the signal first, and then work on it. In addition to that, safety must be given first and top priority when it comes to troubleshooting a dead VFD with speed and utmost efficiency. There can be charges remaining in the capacitors even when they have been plugged out.
