Диагностика кабельных линий энергосистем по тангенсу угла диэлектрических потерь и постоянной времени саморазряда бумажно-пропитанной изоляции

Abstract

The paper suggests extending the experience of impregnatedpaper- insulated power cables technical condition maintenance to power supply system cables. Classification of cable line defects according to dielectric dissipation factor and impregnated-paper insulation self-discharge time constant is introduced. Results of technical diagnostics of power cable lines in operation are given.
