Lightning, inductive load switching, or capacitor bank switching may cause transient overvoltage conditions in AC line voltage applications such as white goods and appliances. Metal Oxide Varistors ...

With the 2020 revision of the NEC, Art. 242 replaced two individual Articles that appeared in earlier editions of the Code — Art. 280 [Surge Arrestors] and Art. 285 [Transient Voltage Surge ...

The National Electrical Code (NEC) requirements for overvoltage protection can be found in Art. 242. This Article is new with the 2020 NEC, and it replaces Art. 280 and Art. 285. Those Articles ...

I love thunderstorms. For some reason, the sound of the heavy rain on the roof almost lulls me to sleep. The sound of distant thunder, caused by occasional flashes of lightning, is comforting to me in ...

Metal-oxide varistors (MOVs) are the most widely used device for protecting sensitive electronics from damaging overvoltage transients. To date, most consider MOVs to be sacrificial devices, expected ...

The widespread adaptation of VoIP gateways in homes and enterprise environments has resulted in increasingly stringent safety requirements for customer premise equipment (CPE). CPE for telecom must ...

Electrical overcurrent, ground faults, arc-flash, and transient overvoltage are major concerns for battery energy storage system (BESS) operators and owners. To protect the system and extend the life ...
