New Concept of High-voltage Switchgear On-line Monitoring System

A new concept of a high-voltage switchgear on-line monitoring system (BMS Bay Monitoring System) is described. Main features and benefits of BMS are simple ethernet-based communication which means simple LAN connectivity with other systems in a switchgear, reliable data collection, reliable controller operation, reliable power supply, quick access to data and a quick and simple retrieval of stored data via graphic user interface (wave shapes, measured values etc.). BMS is modular based system. It can be used as independent system or as a subsystem of integrated on-line monitoring system (PEM-Power Equipment Monitoring). PEM is a complex online monitoring system. It has three integrated on-line monitoring subsystems: rotated machines, power transformers and high-voltage switchgear.
