Abstract

The invention is a device for monitoring the condition of electrical devices with circuit-breaking contacts, such as high voltage breakers, circuit couplers, etc. The device consists of gauges (2, 7) for measuring arc energy, a calculation device (1) for calculating the contact burn-off that corresponds to the measured arc energy, and a presentation device (11c) for registering the degree of the total contact burn-off since the last check.<IMAGE>
