Verification System for On-line AE PD Detectors

Verification System for On-line AE PD Detectors

This system verifies the functionality and performance of on-line AE PD detectors by injecting simulated ultrasonic PD pulses into the power equipment.

Key Features:

•  Comprehensive assessment:The system can comprehensively assess and verify the functionality and performance of on-line

 AE PD detectors, including sensitivity, linearity, stability, sampling continuity, pulse counting, pattern recognition & diagnosis, 

and more.

•  Remote control:Can be controlled both at scene and remotely from a control room.

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

•  Professional-grade acoustic transducer:The acoustic transducer for verification purpose has wide frequency response band 

(10 ~ 300kHz) with flat amplitude-frequency curve within the frequency band.

•  Discharge pattern simulation:Simulates typical discharge patterns including tip discharge, particle discharge, floating 

discharge, air-gap discharge, and creeping discharge.

•  Variable intervals:Pulse repetition rate can be fixed or random, in order to verify the continuity of sampling and the accuracy 

of the pulse count function.

•  Synchronization:Wired or wireless phase synchronization with the power frequency.

•  Automated testing:Highly automated all-in-one software can perform all testing items and generate test reports with one 


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