ZORC™ produce a range of unique high-frequency transient overvoltage surge suppressors for the protection of motors, transformers, generators and filter banks from steep wave-front, short rise-time, high magnitude, spikes, surges and other transient voltages, generated by switching and certain other sources.
The protective characteristics of ZORC™ provide comprehensive insulation coordination with both the CiGRé and IEEE motor impulse voltage withstand characteristics at all practical surge magnitudes and rise times.
Overvoltages are not only related to atmospheric impulses, in reality faults and damage can often be caused by other overvoltages such as switching overvoltage, transient recovery voltages and iron-resonance overvoltages. Good reasons to consider the installation of the ZORC™ surge suppressor.
