Portable Short-Term Online Partial Discharge Monitoring System

A State-Of-The-Art, Portable, Online Partial Discharge Monitoring System for Short-Term PD Monitoring on Electric Power Equipment with Data Diagnostic Software, Cloud Diagnostic Technology, and PD Monitor App

The PDiagnosticM is a portable system t hat utilizes UHF, AE, and HFCT sensor modules to monitor PD signals from Medium and High Voltage power equipment.

The system is ideal for monitoring critical power assets to find and monitor int ermittent PD signals and to analyze the developing PD trends. The PD type is determined by automatic pattern recognition and internal defects can be found at an early stage.

The system provides advanced protection with alarm functions and our Deep Learning data analysis capabi lities utilizing our proprietary Intelligent Cloud Diagnostic Technology.
