ZORC Surge Suppressors

Are unique high frequency transient over voltage surge supressors, for the protection of motors and transformers from steep wave-front, short rise-time, high magnitude, spikes, surges and other transient voltages, generated by switching and other sources.

Switching transients associated with vacuum and other switchgear resulting in expensive insulation failures of motors and dry-type transformers. Pre-striking and re-striking (re-ignition) at the motor or transformer terminals.
