Lab testing of external gas pressure cables and determination of different ageing states
- In the last century external gas pressure cable systems with 64/110 kV operating voltage have proven to form a reliable way for the transportation of electrical energy in larger cities all over the world. The beginning of their development reaches back to the 1930s. The dielectric used in these thermally stable cables consists of a mass impregnated cable paper insulation that requires the absence of partial discharges as a prerequisite for continuous operation. In this contribution two test set-ups for advanced lab testing of external gas pressure cable specimens were established. Two specimens of different aging state were subjected to various electrical voltage levels and frequencies as well as different temperatures. Simultaneously dissipation factor measurement and partial discharge detection were applied. Finally the specimens’ relationships between dissipation factor, partial discharge level, temperature, impregnation mass to paper ratio, water content and external gas pressureIn the last century external gas pressure cable systems with 64/110 kV operating voltage have proven to form a reliable way for the transportation of electrical energy in larger cities all over the world.
