Abstract

Electromagnetic method is one of the proved successfully applied to detect the presence of partial discharge events on electrical insulation. This method applied by utilized an electromagnetic sensor that capable to capture the electromagnetic signals generated by the partial discharge source. The sensors need high sensitivity to be able to capture the very small electromagnetic signals. Thus, the sensors need to be tested its sensitivity to make sure its ability to capture the electromagnetic sensor generated by the partial discharge source. In this research, a Transverse Electromagnetic (TEM) cell is applied to test the sensor sensitivity. The TEM cell is a close cell type which provide better noise insulation and has frequency response up to 1 GHz. The experiment results show the TEM cell can be used to test the sensor sensitivity. The sensor sensitivity is much depending on the sensor dimension. The larger the sensor the higher its sensitivity. Future research should be arranged to test the sensor sensitivity to capture wide bandwidth PD signals.
