An on-line partial discharge monitoring system based on UHF technique for high voltage switchboard is introduced
and four typical discharge models are designed.Then the on-line partial discharge UHF monitoring system is used to conduct PD test on a high voltage seichboard to obtain plenty of discharge patterns and pulse waves
and the phase characteristics of PD are analyzed.The experimental results indicate that the system has the advantages of better anti-interference capability and operating stability to meet the needs of on-line PD monitoring for high voltage switchboard.
