Design of Meander Antenna for UHF Partial Discharge Detection of Transformers
Ultra high frequency (UHF) partial discharge (PD) detection approaches take advantages of strong anti-interference ability, and have been considered as a promising technology for online monitoring PD signals. This paper presents a meander antenna with wide frequency band and small size for UHF PD detection in power transformers. The optimal geometric parameters of the meander antenna were obtai...
متن کاملUhf and Acoustic Partial Discharge Localisation in Power Transformers
The reliability of electrical energy networks depends on the quality and availability of electrical equipment like power transformers. Local failures inside their insulation may lead to catastrophic breakdowns and can cause high outage and penalty costs. Beside the strength and type of a PD, the geometric PD position is of major interest concerning risk evaluation of the flaw. Conventional PD m...
متن کاملPartial Discharge Monitoring of Power Transformers by UHF Sensors
The reliability of electrical energy networks depends on both, the quality and the reliability of its electrical equipment, e.g. power transformers. Local failures inside their insulation can lead to breakdowns and hence to high outage and penalty costs. Usually, power transformers are tested on partial discharge (PD) activity before commissioning. UHF PD monitoring can be used to prevent these...
متن کاملAn 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 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...
