Condition assessment of high voltage insulators in different environments with non-sinusoidal excitation

This project was a step forward in investigating the effect of supply voltage harmonic contents on the measured leakage current of polluted insulators operating in different environments. This study was then used as a basis for developing a sound theoretical understanding of the effects of supply voltage harmonic contents on the measured leakage current characteristics. This study was also used to develop a new condition monitoring index for the polluted insulator under harmonically distorted supply voltage.
