The Transient Earth Voltage (TEV) sensor is a capacitive probe designed to detect local, high‑frequency PD pulses in switchgear, cable sealing ends, machine cable boxes, transformers and other plant. The sensor is very flexible, and can be installed either inside or outside the plant under test. HVPD supply both indoor and outdoor versions of the TEV sensor.
