DC testing of solid dielectric cable is largely ineffective, highly discouraged, and discontinued by most. The preferred method is to use AC voltage to test cables, and for long cable runs, a Very Low ...

When a crew employed by a local electric utility set out to conduct a DC hi-pot test on a new circuit breaker, the task seemed like nothing more than a routine call. Unfortunately, the events that ...

Researchers believe they’ve discovered a new material structure that can improve the energy storage of capacitors. The structure allows for storage while improving the efficiency of ultrafast charging ...

HDW Electronics' SWG series surge generators are designed with switchable, multi-stage surge capacitors and three voltage ranges. This design offers an advantage over single-stage capacitor units by ...

First, let's define a capacitor: It is an electromechanical device capable of storing electrical energy (electrons). It differs from a battery, as a battery produces electrical energy as a by-product ...
