High Voltage Switchgear Monitoring System

Project start: December 2008

Abstract

In the frame of the project, a continuous on-line monitoring system of high voltage switchgear has been developed: including circuit breakers, earth switches, instrument transformers, and surge arresters. Constant monitoring of all these devices enables early warning against certain operation value deviations and trends on particular devices, which could cause faults or material damage to the equipment.

The system enables the timely alarm of the plant staff with the potential to be developed and integrated into an expert system. Equipment maintenance will be done according to the real current state, whereas before it was done through preventive checks and revisions in regular time intervals.
