High Voltage Switchgear Bay Monitoring System - koncar bms Monitoring of high-voltage switchgear provides: • insight into real-time HV switchgear condition • condition based maintenance • incipient fault detection • prevention and reduction of fault consequences (cost reductions) • continuous information on switchgear condition • information about HV switchgear operating conditions (loads at switching operations, assessment of the residual life) • increased availability • fault cause analysis Tools • alarms ■ trend monitoring ■ real-time information • survey of recorded wave shapes and measuring values ■ recommendations for maintenance of the equipment Monitored quantities: Circuit breaker - phase voltage - main circuit current - close coil current - trip coil current - contact travel - hydraulic pressure - SF6 temperature - SF6 dew point - SFe density - close trigger - open trigger - motor trigger - circuit breaker open/closed - gas pressure at 20°C - arc integral - switching times (make, closing, close-open) - contact velocity - variations of gas pressure at various operations - coil current fingerprint comparison / grey zone checking Disconnector - contact travel - motor current - open trigger - close trigger - disconnector open/closed - switching times (make, closing, close-open) - contact velocity Instrument transformer - hydrostatic pressure KONCAR Electrical Engineering INSTITUTE
