1Circuit breaker — For other uses, see Circuit breaker (disambiguation). An air circuit breaker for low voltage (less than 1000 volts) power distribution switchgear …
2Voltage spike — In electrical engineering, spikes are fast, short duration electrical transients in voltage (voltage spikes), current (current spike), or transferred energy (energy spikes) in an electrical circuit.Fast, short duration electrical transients… …
3Voltage multiplier — Villard cascade voltage multiplier. A voltage multiplier is an electrical circuit that converts AC electrical power from a lower voltage to a higher DC voltage, typically by means of a network of capacitors and diodes. Voltage multipliers can be… …
4Voltage regulator tube — A voltage regulator tube (VR tube) is an electronic component used as a shunt regulator to hold a voltage constant at a pre determined level.Physically, these devices resemble vacuum tubes, but there are two main differences: * Their glass… …
5Voltage of a circuit — (Electric utility) The electric pressure of a circuit, measured in volts. Usually a nominal rating, based on the maximum normal effective difference of potential between any two conductors of the circuit. California Energy Comission.… …
6Extra-low voltage — IEC voltage range AC DC defining risk High voltage (supply system) > 1000 Vrms > 1500 V electrical arcing Low voltage (supply system) 25–1000 Vrms 60–1500 V electrical shock Extra low voltage (supply system) < 25 V …
7High 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… …
8integrated circuit — Electronics. a circuit of transistors, resistors, and capacitors constructed on a single semiconductor wafer or chip, in which the components are interconnected to perform a given function. Abbr.: IC Also called microcircuit. [1955 60] * * * ▪… …
9Crowbar (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… …
10Open circuit test — The Open circuit test, or no load test , is one of the methods used in electrical engineering to determine the no load impedance in the excitation branch of a real transformer. Contents 1 Method 2 Calculatio …
