Surge arrester with means for measuring transient overvoltages

摘要

In order to a surge arrester (1) for protection of electronic high-voltage devices with a take-off conductor housing (2), a high voltage terminal (4) and a ground voltage connection (6), which, by means of a take-off conductor of the current paths (9) can be connected to one another, one in which the output conductor current path (9) arranged non-linear resistor (10), which consists of a series circuit composed of non-linear resistors (10a, 10b, 10c, 10d, 10e, 10f) is formed, and to provide, with the fast transient overvoltages can be detected in a simple and cost-effective manner, it is proposed that voltage detection means (12) to detect a at a measuring resistor (10e, 10f) are set up of the voltage dropping, wherein the measuring resistor (10e, 10f) of one or more non-linear resistor elements is formed.
