Abstract

See full text

A method for testing mainframe performance of different types of PD detectors based on analog voltage signal injection, the method comprises: using a function generator (19) with an adjustable output frequency of 0 to 3.5 GHz and an adjustable output amplitude of 0 to 10V, directly injecting or injecting via a DC blocking element (28) with a frequency band of 10 kHz to 10 MHz equivalent analog voltage signals generated by said function generator (19) based on PD waveforms actually tested by a pulse current PD detection sensor (6), an ultrasound PD detection sensor (12,13) and a UHF PD detection sensor (9) into mainframes of a pulse current PD detector, an ultrasound PD detector and a UHF PD detector respectively. The advantages are that the test method is universalized and standardized, the test result is reproducible and measurable, the application scope of the test object is wide, and the test content is comprehensive.
