Protection of Electronic Circuits from Overvoltages
A varistor with a parasitic capacitance of 2 nF has an rms current of 0.09 mA
when installed between line and ground on mains with a nominal voltage of 120
V rms and a frequency of 60 Hz. Such a varistor has an inadequate safety margin
to ...

The Circuits and Filters Handbook, Second Edition
A voltage dependent resistor (VDR), called a varistor, is a resistor whose
characteristic V versus / is not a straight line and a small change of voltage
causes a significant change of current according to the equation V = C/P (10.9)
where P is ...

DC/AC Circuits and Electronics: Principles & Applications
The varistor is still another two-terminal device. Its schematic symbol and
characteristic curve are shown in Figure 4-20. The varistor, like the diode, is
sensitive to the voltage across it. However, the varistor is designed to conduct at
a specified ...
The voltage applied across the terminals when a current of 1 mA flows through
varistor is called varistor voltage. 2.9.2 Application The main application of
varistor is the protection of circuits from transients, spikes, surges and impulse
voltages.

Flexible Ac Transmission Systems (FACTS)
Following fault initiation in the surrounding network, high current flowing through
the series capacitor will result in a correspondingly high voltage across the
capacitor and the ZnO-varistor. The high voltage causes the varistor to conduct ...
