This video explains how capacitors work and why they are essential in modern electronics. Capacitors store and release ...

When it comes to the most typical cause of poor power factor in a facility, motor inductance is a likely culprit. The problem worsens when motors are not loaded to their full capacity. Harmonic ...

FIGURE 1: This electrical schematic diagram shows the cooler’s single-phase, R-134a capacitor start/capacitor run (CSCR) refrigeration compressor motor, and starting relay circuit section. July 6, ...

As an industrial electrician, you'll encounter many complex electrical circuits and drives that will break down as they age. Chances are, you won't be an expert in repairing these devices, but you can ...

A couple of years ago, I had the privilege of designing and building a new, state-of-the-art 50 kW transmitter site facility for KBRT(AM) in the Los Angeles market. The project was well documented in ...

The B3270xP series of ultra-small, MKP film capacitors from TDK are tailored for power-factor-correction stages in power ...

While passive precharge employs a power resistor to create an RC circuit that charges the capacitor asymptotically, active precharge can employ a switching converter with a buck topology that uses ...

A simple ohmmeter is all that is needed to troubleshoot a potential relay. After taking all of the connecting wires off of the potential relay, measure the resistance across the 1 and 2 terminals. The ...

This video explains what capacitors are and how they store and release electrical energy in electronic circuits. Capacitors ...
