Transient Earth Voltage (TEV)

TRANSIENT EARTH VOLTAGE (TEV) SENSORS

TRANSIENT EARTH VOLTAGE (TEV) SENSORS are designed to detect local and high frequency PD pulses in switchgear, cable sealing ends, transformers and other plant. It is a compact, electromagnetic sensor capable of detecting high frequency radiation that is coupled onto an earthed metal surfaces from local PD within switchgear, bushings and other plant. TEV can be used to make on-line PD measurements in decibels (dB).

Figure 8 Transient Earth Voltage (TEV)

The TEV sensor can be magnetically attached or bolted to the outer surface of metal-clad switchgear typically on cable boxes or next to cable terminations. Also available is the outdoor type.

TEV sensor installed on switchgear Permanently installed to the inner surface of the switchgear housing using permanent clip.

TEV sensor attached to switchgear. Magnetically attached to the outside of the switchgear.

The TEV outdoor type fully weatherproof, installed on HV cable sheathing. Installed on the outer metalwork or earthed parts of the HV cable sheathing using a securing strap.

All types of these sensors are compatible for use with the HVPD Kronos Permanent and HVPD Kronos Spot Tester.
