Handheld Partial Discharge Detector

Advanced Handheld Partial Discharge Detector for Electric Power Equipment with Multi-Sensor and Cloud Diagnostic Technologies, Data Management Software, and Test Management App.

The PDetector is an ideal device for On-Line Partial Discharge (OLPD) testing of MV and HV equipment which employs all 5 types of OLPD sensor technology: Ultra-High Frequency (UHF), Acoustic Emissions (AE), Ultrasonic, High Frequency Current Transformer (HFCT), and Transient Earth Voltage (TEV). The information from multiple sensors gives the PDetector the versatility to detect all types of PD in all types of substation apparatus. The exact type of PD activity can be determined effectively using multiple on-screen data spectrum analysis. The PDetector greatly simplifies and standardizes the routine OLPD testing procedure by using the intelligent patrol function, the App, and the PMDTCloud. It is a very powerful and helpful tool for substation operators to conduct routine testing in a substation quickly, to determine what the issue is, and where it is located.
