Summary
Documents
Partial Discharge (PD) is the primary cause of disruptive failure of High Voltage (HV) switchgear. The UltraTEV Alarm system continuously monitors for PD activity and alarms, using GPRS, when levels exceed threshold limits, allowing timely intervention by the DNO. This in turn enhances the way in which HV assets are managed and maintained and is making a positive impact on the safety of operators working within substations.
Objectives
The UltraTEV Alarm measures transient earth voltage and ultrasonic PD activity at substation sites, and employs an algorithm to detect PD anomalies which it then provides location tagged alarm to a central hub.
