WebJan 16, 2024 · The varistor becomes highly conductive once the rising voltage exceeds the rated or clamping voltage (250V), about 1mA of current begins to flow through the varistor. The resistance of the varistor becomes small when the transient voltage across the varistor is equal to or greater than the clamping voltage, which transforms it into a … Webdiodes, and metal oxide varistors. The clamp-type devices have faster response times but are limited in their current handling ability because most of the energy of the transient must be dissipated by the clamping device.Also, the voltage drop across a clamp-type surge protector increases with the conducted current as shown in Figure 2A.

Webselection of the varistor voltage should refer to the equation V 1mA =K* Vp, K=(1.5~2). Its aging coefficient, varistor voltage tolerance and power quality should be considered. Vp: it is the voltage peak of the circuit. For example, the voltage peak is 310V for a circuit of 220VAC. The coefficient is taken from the range of 1.5~2. Webcircuit voltage exceeds the varistor clamping voltage. The energy deposited into the ceramic material increases as the surge diversion is longer when clamping occurs at a …
