PDetector

Advanced Handheld Partial Discharge Detector for Electric Power Equipment with Multiple Sensors and Data Management Software

The PDetector is an ideal device for Online 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. 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.

Main Features 

  • Employs 5 types of online PD sensor technologies

  • PRPD, PRPS, Single-Cycle, Phase, Waveform, and Amplitude Spectrums to determine PD types 

  • Wireless connection to UHF and HFCT sensors

  • Power/Light frequency synchronization

  • Intelligent Patrol Function to create a test task with a set standard test procedure to improve test efficiency

  • RFID asset tagging on power equipment to standardize the field OLPD testing procedure to greatly improve test efficiency and achieve asset management

  • One-key data saving and simple operation, ideal for quick PD testing for a whole substation   

  • Records up to 5 minutes of video while in the PRPD/PRPS detection modes of the UHF/HFCT Sensors

  • PC-based data management software with automatic report generation function in JPEG/MS Word formats

  • On-board data storage

  • Environmentally friendly and supports paperless testing

Data Management Software

The PDetector data management software is a powerful, PC-based tool that stores, manages, analyzes the test data, and manages the test jobs.

  • Test File Management: manages the online testing data files of the power equipment and substations.

  • Test Job Management: creates, issues, manages test jobs and archives the test data. 

  • Test Data Management: stores and manages the test data spectrums collected by the PDetector and provide trend analysis. There are 12 kinds of PD and infrared test data including spectrums, audio and video.

  • Intelligent Patrol Function: creates a new test job on software and download it to the PDetector main unit. Patrol the substation and test for PD efficiently.
