The primary defense to protect electrical equipment from over-voltages is surge arresters. These necessary devices hold metal oxide varistors (MOVs) and are rapid response protectors against voltage ...

The wSeries wireless transmitters for analog voltage and current, temperature, humidity and barometric pressure communicate on an 802.11 b/g Wi-Fi network. Designed for demanding industrial ...

KOA Speer Electronics has launched the NV73S series of multilayer metal-oxide varistors, which handles a surge current of up to 6,000 A, claiming five times higher protection than existing products.

Varistor ceramics, predominantly based on SnO₂, are engineered to exhibit a highly non‐ohmic current–voltage relationship that is critical in safeguarding electrical circuits from transient voltage ...
