Abstract

Asset condition monitoring through Partial Discharge (PD) measurements is widely used for pre-emptive maintenance especially in cable networks. Several monitoring systems rely on measurements in the High Frequency (HF) band using wideband sensors when it comes to PD monitoring to have higher Signal to Noise Ratios (SNR), ignoring the radical attenuation of the higher frequencies by the cable. This paper presents measured values of attenuation from measuring loops and several other important insights that can help in the interpretation of PD measured data.
