Vvaristor, certain types of faults on the utility power grid can result in sustained over-voltage conditions. Yueqing Hecheng Electrical Co. Susceptibility of electronic equipment to these other power disturbances is defined by other aspects of the system design, either inside the equipment itself or externally by means such as a UPS, a voltage regulator or a surge protector with built-in overvoltage protection which typically consists of a voltage-sensing circuit and a relay for disconnecting the AC input when the voltage reaches a danger threshold.
Circuit of the traditional construction of varistors used as click suppressors in telephony. A varistor is an electronic component with an electrical resistance that varies with the applied voltage.

However, they can handle significantly faristor fault currents and withstand multiple high-voltage hits for example, from lightning without significant degradation. Archived from the original on Other applications for varistors in the telephone plant included protection of circuits from voltage spikes and noise, as well as click suppression on receiver ear-piece elements to protect users’ ears from popping noises when switching circuits.
Grisdale in the early s was varjstor to guard telephone lines from lightning. Piezoresistor Varistor Varistor Cnr14dk 14dk Resistors. Haven’t found the right supplier yet? A varistor remains jjvr as a shunt -mode device during normal operation when the voltage across it remains well below its “clamping voltage”, thus varistors are typically used for suppressing line voltage surges.
The boundary between each grain and its neighbour forms a jvvr junction, which allows current to flow in only one direction. Its non linear exponent characteristic, broad range and mass production makes this product suitable for. Traditionally, varistors were indeed constructed by connecting two rectifiers in anti-parallel configuration.
Another method for suppressing voltage spikes is the transient-voltage-suppression diode TVS.

Manufacturer’s life-expectancy charts relate currentseverity, and number of transients to make failure predictions based on the total energy dissipated over the life of the part. Metal oxide varistor transient vi characteristics curves. Wikimedia Commons has media related to Varistors.
Retrieved 9 April The copper-oxide varistor exhibited a varying resistance in dependence on the polarity and magnitude of applied voltage. On long loops, the varistors maintained variator relatively high resistance and did not alter the signals significantly.

Other sustained and harmful overvoltages vagistor be lower and therefore ignored by a MOV device.
At low voltage the varistor has a high electrical resistance which decreases as the varkstor is raised. In the most common type of surge protector, a component called a metal oxide varistor, or mov, diverts the extra voltage.
