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 ...
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 ...
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, ...
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 ...
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 ...
