Abstract :
This paper describes the GHz order electromagnetic (EM) wave generator we have developed that simulates UHF band aerial noise occasionally measured in HV substation. Using this generator and the model GIS, we investigated the invasion properties of such UHF band aerial noise into the model GIS by changing the location of the generator, i.e. partial discharge (PD) source. As a result, PD-induced EM wave generated outside GIS can invade into GIS inside with GHz order frequency component if PDs were generated near the GIS components worked as an aperture for EM wave.
