PD investigation

New from EA Technology is a powerful, versatile portable system for investigating and recording Partial Discharge (PD) activity in live MV and HV assets. Called the UltraTEV Locator, the dual probe instrument features six different sensor technologies to detect and gather information about PD activity, which EA Technology says is a factor in 85% of disruptive substation failures.

Each of the UltraTEV Locator's probes use ultrasonic and Transient Earth Voltage (TEV) sensors to locate and measure PD activity both on the surface of assets and internally. PD activity in cables is measured using a plug-in Radio Frequency Current Transfer (RFCT) sensor.
