Verification System for On-line UHF PD Detectors

Verification System for On-line UHF PD Detectors

This system assesses and verifies the functionality and performance of on-line UHF partial discharge (PD) detectors by injecting picosecond pulses or simulated UHF partial discharge signals into the power equipment.

Key Features:

•  Comprehensive assessment:Comprehensively assess and verify the functionality and performance of on-line UHF PD 

detectors, including sensitivity, linearity, stability, sampling continuity, interference resistance, pulse counting, pattern 

recognition & diagnosis, and more.

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

•  Professional RF antennas:Various professional antenna options for different applications; Also has built-in backup antenna.

•  Picosecond pulse generator:Generates picosecond pulses and simulated PD signals with adjustable amplitude, frequency, 

and interval.

•  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 pulse 

count functionality.

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

•  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.
