Electrical Breakdown Characteristics and Testing of High Voltage XLPE and EPR Insulated Cables

Abstract

Threshold voltages and other basi c breakdown characteristics, spanning times from microseconds to cable life expectancy, were determined for cross-linked inked polyethyene ( XLPE) and ethylene propylene rubber (EPR) cables. These results are based upon measurements of 60Hz, high frequency, impulse, and impulse with d.c. bias voltages.
