Portable Online Partial Discharge Diagnostic and Location System

Portable, Trouble-Shooting Online Partial Discharge Diagnostic and Location System for Electric Power Equipment that Utilizes Multiple Sensors with Advanced Diagnostic Software and Accurate PD Location Capabilities

The PDiagnostic is a portable system that utilizes Ultra-High Frequency (UHF), Acoustic Emissions (AE), High-Frequency Current Transformer (HFCT), and Transient Earth Voltage (TEV) sensors to detect, analyze, and locate the PD signals in real time for a multitude of medium and high voltage electric power equipment.

The multi-channel PDiagnostic system locates PD on power equipment down to the measurement of a meter by utilizing Acoustic-Electromagnetic Combination Location Technique, Time Difference of Sig nals' Arrival (TDOA), Partial Discharge Signals Separation (PDSS), and 3D Positioning Technology with PC software included.

The system features advanced PD diagnostic, automatic PD type pattern recognition, and accurate PD Location capabilities. The PDiagnostic is an ideal trouble-shooting tool for your PD programs. Severity is determined and maintenance suggestions are provided accordingly.
