This paper presents the results of impulse tests performed at Ontario Hydro on a portion of a motor winding. The objective of these EPRI funded tests was to determine the wave propagation properties of the motor coils. In all cases, surge voltages we

It is shown that station entrance surge arresters are not required to maintain adequate protective margins in a proposed SF6 substation connected by HPOF pipe-type cables. This results in substantial cost savings for this installation. A calculation

This report presents a simplified silicon-carbide surge arrester model suitable for analog and digital studies of switching transients on overhead HV and EHV lines. The report also includes a guide for the application of the model in the selection of
