Abstract

The present invention provides for a circuit arrangement, and related method, for monitoring the operative state of a voltage-limiter device such as, for example, a surge arrester and in a manner to identify an error currents flowing there-through and which can prove indicative of deterioration in the state of the device and which proves particularly advantageous in providing or such monitoring even if only small error currents are likely, but in a manner which still allows for the required operation of the portage limiter device and for example during circuit protection against current surges.
