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.
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.
