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 ...

Seaward has introduced the first instrument of its type for the safe discharge of stored energy in large capacitors and electrically charged equipment. The portable new SD300 is a highly innovative, ...

A perennial challenge in power-supply design is the safe and speedy discharge, or “dump,” at turn-off of the large amount of energy stored in the postrectification filter capacitors. This energy, CV 2 ...

The new capacitor is much smaller than a conventional device. (Courtesy: Nanyang Technological University) Researchers in Singapore have developed a prototype polymer capacitor that can store much ...

Many power supplies use hold-up capacitors to keep enough energy at the full-wave or bridge rectifier output to supply a load when the rectified voltage drops and rises again at the next half-cycle of ...

Our fundamental passive and inherently analog components—resistors, capacitors, and inductors—are so conceptually simple and easy to describe that we often don’t fully articulate or appreciate the ...

Over the last 40 years, a series of misconceptions regarding mica capacitor applications has led novice users to consistently over-derate wound or rolled mica/epoxy dielectric capacitors. The mined ...
