Transient Earth Voltage Sensor

iTEV sensor can be magnetically attached to the outer surface of the metal-clad switchgear, typically on cable boxes or next cable boxes or next to cable termination, to detect TEV signal representing PD inside. Then, TEV signals can be measured by an oscilloscope to obtain partial discharge pattern. The results revealed that each defect has own characteristic that differs from each other.
