Abstract
Detection of partial discharge (PD) in the frequency range ultrawide band (UWB) provides some benefits such as in a more accurate observation of the PD pulse shape and the PD frequency spectrum. One method to measure the PD signals in the UWB frequency range is by using the PD detecting impedance circuit. The 50 ohm detecting impedance is used as a coupling device to maximize power transfer of PD current. This paper design the matching impedance circuit comprising an impedance detector as attenuator and UWB amplifier as a signal amplifier. S-parameter characteristics of the circuit is simulated in software Advanced Design System (ADS) software. The PD detecting circuit is made and it is tested using Vector Network Analyzer (VNA) instruments. Then, the circuit is used to measure PD on the needle — plates electrode in the air.
