On-line Partial Discharge For Power Transformer Detection Method Of Beijing Electric Power Company

Partial discharge measurement is currently the test characteristics of electrical equipment and found that the internal defects in equipment to prevent equipment failure of a very effective means.Power enterprises to meet the needs of modern, ultra-high frequency method,ultrasonic method,chromatography and many other oil-line partial discharge detection techniques can be developed and applied in reality.This paper introduces the main transformer power companies,Beijing-line partial discharge detection techniques applied research,the measurement of partial discharge analysis techniques,and accumulated a large amount of data,sample and experience,given the application of the two typical cases,introduced DMS UHF and VHF TECHIMP two methods of advanced technology,a typical pattern of a typical.The establishment of a wide range of online partial discharge detection methods combined with a reasonable diagnostic method for the future of power equipment to provide online guidance to the development of detection methods.
