Abstract

The invention relates to a condition monitor for a switchgear device in an electrical power distribution system. The switchgear device is arranged with an electrically powered actuator for operating a moveable part of the switchgear device, for example, operating the opening and / or closing of a circuit breaker. The switchgear device has a control unit with means to receive state information from the actuator, and panel means to present information via an HMI. The HMI may be accessed remotely. In other aspects of the invention a method, a human-machine interface and a computer program for carrying out the method are described.

Description

technical field [0001] The present invention relates to condition monitors for equipment in power distribution systems. In particular, it relates to a condition monitor for electrical distribution equipment including an electric actuator which is a type of Devices such as circuit breakers. Background technique [0002] Power distribution systems for industrial and residential electricity consumers use a variety of equipment comprising one or more moving parts, most of which are installed outdoors. Such equipment includes eg circuit breakers, earthing switches, overload protection devices. A circuit breaker is an example of electrical distribution equipment that has one or more moving parts. Different types of circuit breakers are used to control and regulate power distribution, to switch power on and off, and to switch power from or to different power lines or feeders, as required. A circuit breaker must be able to break and make normal current loads and, above all, must...
