How to Prevent the high Inrush Current in Capacitor Switching?

Introduction to High Inrush Current in Capacitor Switching Applications of capacitance switching are not only restricted to capacitive currents but they have their implementation in energizing process of capacitors banks, overhead lines and cables. Capacitors banks switching are known to be cause of very large value of transient voltage...

HRC Fuse (High Rupturing Capacity Fuse) and its Types

HRC Fuse (High Rupturing Capacity Fuse) and its Types This type of fuse contains a fuse wire in it, which carries the short circuit current safely for a given time period. During this period, if fault is removed, then it does not blow off otherwise it will melt and remove the circuit from electrical supply hence, the circuit remains safe. The...
