Abstract
An overvoltage arrester for high voltages having a high-voltage terminal that is connected to an arrester block forming a nonlinear resistor, and a temperature sensor for detecting the temperature of the arrester block. In order to enable a simple and reliable detection of the temperature of the arrester block continually during the operation thereof, the temperature sensor detects a change of the longitudinal extent of the arrester block.
