This paper deals with partial discharge (PD) current waveforms in transformer oil measured with the SHF_PDPW (super high frequency wideband PD current pulse waveform measurement) system that enables us to obtain accurately waveforms up to SHF band (3–30GHz). We investigated the PD current pulse waveform, especially on the rise time, the current peak, and the charge quantity obtained by the time integral...
As for the insulation diagnosis of the electric power apparatus and the measurement of electromagnetic interference (EMI), a position location technique of the electromagnetic(EM) wave radiation source is required. Although there are many researches on the position location technique of the EM wave radiation source, it still remains the difficulties to readily understanding the result, i.e., the position...
