Products Name:
Portable PD Tester

Overview
All of our portable PD probes adopt non-intrusive detection modes to achieve PD detection and positioning; they are suitable for on-line detection and diagnosis of insulation defects of various high-voltage electrical equipment, and the test results can be obtained in several seconds, so they are effective means for status detection and fault diagnosis.
Model Selection Guide
Model | Principle |
HNPJF-A2 | Electromagnetic wave and ultrasonic in-vitro sensing principle (AE) |
HNPJF-T2 | Transient earth voltage (TEV) |
HNPJF-U2 | Ultra-high frequency (UHF, 0.3-3GHz) |
HNPJF-Z100 | Three-in-one comprehensive type |
Main Features
The instrument is simple and practical, its functions are easy to set, and sound-light alarms are given automatically when PD signals are detected.
GIS in-vitro sensing, no need to remove any parts of GIS, and no influence on GIS operation
Easy to carry, convenient for on-site inspection, and simple and easy to operate, increasing the work efficiency
Good anti-electromagnetic interference, and resistant to influences such as corona discharge in the air, and mobile phone communication
Filtering out external interference signals with the noise sensor to improve the reliability of PD signal identification
Good detection sensitivity, and detection sensitivity to metal particle and floating potential body discharge, etc. up to 5PC
Battery-powered, no power cable required: the fully-charged battery lasts 8 hours, while the AC power supply is supported
