High voltage switchgear — is any switchgear used to connect or disconnect a part of a high voltage power system. These switchgear are essential elements for the protection and safe operation, without interruption, of a high voltage power system. This type of equipment is… … Wikipedia
Circuit breaker — For other uses, see Circuit breaker (disambiguation). An air circuit breaker for low voltage (less than 1000 volts) power distribution switchgear … Wikipedia
High-voltage direct current — HVDC or high voltage, direct current electric power transmission systems contrast with the more common alternating current systems as a means for the bulk transmission of electrical power. The modern form of HVDC transmission uses technology… … Wikipedia
High Voltage Isolation and Ground Potential Rise — This article outlines the principles of High Voltage Isolation (HVI) and Ground Potential Rise (GPR). Most often questions of concern arise to anyone associated with the use of any communication signal (analog or digital) via a metallic or fiber… … Wikipedia
Earth leakage circuit breaker — An Earth Leakage Circuit Breaker (ELCB) is a safety device used in electrical installations with high earth impedance to prevent shock.PurposeMany electrical installations have a relatively high earth impedance. This may be due to the use of a… … Wikipedia
Transient Recovery Voltage — A transient recovery voltage (or TRV) for high voltage circuit breakers is the voltage that appears across the terminals after current interruption. It is a critical parameter for fault interruption by a high voltage circuit breaker, its… … Wikipedia
Contact breaker — Breaker arm with contact points at the left. The pivot is on the right and the cam follower is in the middle of the breaker arm. A contact breaker (or points ) is a type of electrical switch, and the term typically refers to the switching device… … Wikipedia
Arc-fault circuit interrupter — An arc fault circuit interrupter (AFCI) is a circuit breaker designed to prevent fires by detecting non working electrical arcs and disconnect power before the arc starts a fire. The AFCI should distinguish between a working arc that may occur in … Wikipedia
Crowbar (circuit) — A crowbar circuit is an electrical circuit used to prevent an overvoltage condition of a power supply unit from damaging the circuits attached to the power supply. It operates by putting a short circuit or low resistance path across the voltage… … Wikipedia
Ring circuit — In electricity supply, a ring final circuit or ring circuit (informally also ring main or just ring) is an electrical wiring technique developed and primarily used in the United Kingdom that provides two independent conductors for live, neutral… … Wikipedia
Prospective short circuit current — The prospective short circuit current (PSCC) is the highest electric current which can exist in a particular electrical system under short circuit conditions. It is determined by the voltage and impedance of the supply system. It is of the order… … Wikipedia
