Many single-phase motors used on refrigeration systems will incorporate some type of capacitor. They will either use a start capacitor to aid in its starting or a run capacitor to improve its running ...

Single-phase motors, adjustable-speed drives (ASDs), and power factor (PF) correction applications often depend on capacitors to operate properly. This article explains how to test these critical ...

In the past five to ten years, there has been a big shakeout in the capacitor industry with at least 15 major manufacturers ceasing production for various reasons. Product lines have also been ...

Solid-state ac supplies replace motor-generator and tap-changing transformers to offer the same tests at the push of a button • Solid-state ac-power sources combine the variable-frequency and ...

Capacitors behave differently than resistors, where resistors allow a flow of electrons through them directly proportional to the voltage drop, and capacitors oppose changes in voltage by drawing or ...

When employing electrolytic, ceramic, and film capacitors in various configurations for high ripple current applications, you run the risk of stressing the capacitor, which leads to premature failure.

High Voltage, Inc.'s VT- 33 offers complete cable care for underground shielded power cables up to 25 kV class. It a VLF AC cable testing and fault finding/burner instrument in one self-contained ...

Within the body of a high-voltage multi-layer ceramic capacitor, a gap-type defect is beginning its career of destruction. The defect may be a void within the ceramic dielectric, a crack within the ...
