The RTD and the SSC wiring act as an antenna. As the PD pulse travels in the vicinity of the RTD and the SSC wiring the PD energy is coupled to the RTD and SSC. The pulse then follows the RTD, SSC wiring out to the transducer in common mode (between all wires and ground) where the PD pulses are extracted from the wiring and feed to the monitor or analyzer. In order to make sense out ofthe PD signals an appropriate analyzer to decipher the signals for analysis is required, ost of the medium voltage machines already have RTD detectors embedded into the winding by the manufacturer and these detectors can be used for partial discharge measurements.
