An Intelligent Sensor for the Ultra-High-Frequency Partial Discharge Online Monitoring of Power Transformers
Ultra-high-frequency (UHF) partial discharge (PD) online monitoring is an effective way to inspect potential faults and insulation defects in power transformers. The construction of UHF PD online monitoring system is a challenge because of the high-frequency and wide-frequency band of the UHF PD signal. This paper presents a novel, intelligent sensor for UHF PD online monitoring based on a new ...

متن کاملPartial discharge signal detection using ultra high frequency method in high voltage power equipments: a review
Partial discharge (PD) can be detected using ultra high frequency (UHF) method to increase the detection threshold and to improve the performance of on-line measurement of PD in noise environment. The PD emitted energy as electromagnetic emission, acoustic emission and ozone and nitrous oxide gases. We can use this emitted energy to detected PD signal. The best method to detect PD in gas insula...
متن کاملSuitability of Ultra High Frequency Partial Discharge Measurement for Quality Assurance and Testing of Power Transformers
Well known reasons for local failures in power transformers are caused by partial discharges (PD) in the electric insulation. Continuous deterioration over time increases the defect which finally can lead to a breakdown of the entire insulation. The importance of PD measurement is accommodated by standardized electrical measurement according to IEC 60270 [1] which is required for acceptance cer...
