Space charge distribution and leakage current pulses for contaminated glass insulator strings in power transmission lines

This study reports an investigation on space charge distribution and leakage current (LC) pulses of four units of glass insulators recently removed from service. Simulation works were conducted using finite element software and validated by laboratory experiments. The simulation and experimental res...
