HV Equipment

Portable PD Detector (PPDD)


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.
