Efficient PD Detecting

PDProbe is a rapid survey tool for Partial Discharge detection, utilizing different types of sensor including TEV, RFCT, UHF, Acoustic and Ultrasonic for different applications. Through its dual channel design, simultaneous results from two separate sensors can be compared in order to reduce unnecessary sensor switching for comparison. Dual channel reading will be displayed, one from electromagnetic channel plus one from audible channel.

Built-in NFC is an innovated asset manage- ment function, that allows on-site testing engineer to improve testing procedure and accuracy.
Enhanced Analysis Function

Enhanced Analysis Function

Dual magnitude display, PRPD and PRPS are basic functions of PDProbe. With the aid of PDS’s Big Data technology, PDProbe has built-in signal auto-analysis and recognition function to help the user to distinguish different types of discharge and noise.
