The PDiagnosticM is a portable system that 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 intermittent 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 capabilities utilizing our proprietary Intelligent Cloud Diagnostic Technology.

Asset Condition Monitoring and Diagnostic Data Management System

The PMDTCloud is a cutting-edge, cloud-based asset condition monitoring and diagnostic data management system software that communicates with various of our products to collect and analyze the test/monitoring data. It is developed based on the innovations in internet technologies and the Internet of Things. It employs a multi-dimensional cloud diagnostics algorithm developed by PMDT by utilizing the latest big data computing, cloud calculation, and deep learning technology based on our abundant on-site field test data collected through the years.   


The PMDTCloud provides users with a faster method to access the latest data and condition of the power assets from any authorized web enabled device via a login with a user ID and password. Diagnostic results (normal, early warning, or alarm), PD types, and PD trends are provided.  


The PMDTCloud includes the following functionality: deep learning, cloud diagnostic, test job/project management, alarms, report generation, and operational status indicators of the substation(s).


The PDiagnosticM connects to the PMDTCloud via a 3G/4G/internet connection to transmit the monitoring data. The data is analyzed by the Cloud utilizing advanced Deep Learning Technology.
