Abstract

The invention relates to a method for evaluating the state and the quality of low-voltage networks, in the branched system of which there is a plurality of connected loads, by determining network measurement data by means of power quality measuring and testing devices and transferring the network measurement data, by means of a standard interface, to a control system or in retrievable form to a server. According to the invention, the overvoltage protection devices, which are or can be used in the low-voltage system and have a self-diagnosis unit and an existing wireless or wired standard interface for data transfer, are able to determine network measurement data by means of integrated or adapted power quality measuring and testing devices.
