要約(日本語): Radio sensing systems for detecting PD has been developed for power equipment. Superheterodyne spectrum analyzer (SA) has been widely used for receiving EM waves emitted from PD because of its high sensitivity. Generally, resolution bandwidth (RBW) of intermediate frequency filters, which is implemented in SA, is shown as a measurement parameter. Wide RBW is used for the narrowband UHF method by using the zero span mode of SA. However, it is not suitable for obtaining the accurate frequency spectra because of low frequency resolution. In the previous paper, we investigated the effect of RBW and the impulse bandwidth of SA on the pulse responses.This paper describes the effect of RBW of SA on the measurement of EM waves emitted from PD in multipath-rich environment, such as transformers, cubicles, and underground substations.
