HV Equipment

Portable PD Detector


The Portable PD Detector allows for testing and the quick evaluation of switchgear, cables, and other HV equipment with integrated transient earth voltages (TEV) and non-contact ultrasonic (AA) sensors. The handheld detector is also equipped with a standard BNC interface to allow for the connection of an external HFCT sensor for PD testing of cables. A large integrated LCD display shows the real-time measurement results as a function of amplitude, pulse number, severity, phase-resolved PD pattern, and phase-resolved pulse sequence. Waveform recording can be activated automatically or manually with the ability to save onto a flash drive and export the results via USB or WIFI connection.
