Here's how to reduce the effect of capacitor switching on your power system Last month's article discussed exactly what happens when electric utilities switch shunt capacitors: power system components ...

Restrikes or re-ignitions occur when the dielectric strength of the open gap, during contact parting, is not great enough to withstand the recovery voltage across the open gap. With a capacitive load, ...

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 ...
