Assessment and Verification System for HF PD Detectors

Assessment and Verification System for HF PD Detectors

This system assesses and verifies the functionality and performance of HF PD detectors by injecting HF pulses or simulated HF partial discharge signals into the detector’s calibration circuit.

Key Features:

•  Comprehensive assessment:Comprehensively assess and verify the functionality and performance of HF PD detectors, including impedance, transfer-ratio, sensitivity, linearity, frequency band, stability, sampling continuity, interference resistance, pulse counting, pattern recognition & diagnosis, and more.

•  HF pulse generator:Generates HF pulses and simulated PD signals with adjustable amplitude, frequency, and interval.

•  Interference simulation:Simulates interference on different frequencies to assess the subject’s ability to resist interference.

•  Discharge pattern simulation:Simulates typical discharge patterns including tip discharge, particle discharge, floating discharge, air-gap discharge, and creeping discharge.

•  Pulse counting verification:Generates pulses with fixed or random intervals to verify the continuity of sampling and the accuracy of the pulse count functionality.

•  High compatibility:Suitable for HF sensors with various sizes and structures.

•  Simulation platform:Dual circuit design with low attenuation and easily matched impedance.

•  Automated testing:Highly automated all-in-one software performs all testing items and generates test reports with one click.

•  Data storage:Can store the records of all assessed instruments for diagnosis and analysis.
