چکیده
New transient suppressors using meta l oxide varistors offer improved protection of appliances and consumer electronics against overvoltages. This improvement, however, could be at t h e risk of imposing excessive duty on t h e suppressor in case of a very severe lightning s t roke near the house where these suppressors a r e installed. A simulated house wiring system was subjected to three levels nf !Ig.h.tging currents injected into t h e ground wires (moderate, severe, extremely severe), with various combinations of suppressors installed alone or in a coordinated com bination.

متن کاملInternal Protection of Transformer Windings Against Transeint Surges Using ZnO Varistors
Power system overvoltages due to switching, lightning and other disturbances are the main problem for designers of the power transformers. Once some frequencies of the incoming surges match with some of the natural frequencies of transformer winding, the resonance phenomenon is expected in transformer winding. The resonant overvoltages may destroy the insulation between turns and cause to insul...

متن کاملRecognition of Traveling Surges in HVDC with Wavelet Entropy
Traveling surges are commonly adopted in protection devices of high-voltage direct current (HVDC) transmission systems. Lightning strikes also can produce large-amplitude traveling surges which lead to the malfunction of relays. To ensure the reliable operation of protection devices, recognition of traveling surges must be considered. Wavelet entropy, which can reveal time-frequency distributio...
