Test Report on Energy-Saving DAC High-Speed Cable
This edited past contribution to INMR by Paul Leufkens of Power Projects Leufkens in the United States along with Prof. Edward Gulski and Rogier Jongen at onsite hv solutions in Switzerland, focused on application of DAC for after-laying testing and diagnostics of all types of. IEC standards for power cable systems up to and above 150 kV rated voltage are manufacturer standards and, according to experts, do not necessarily provide adequate recommendations for testing after-installation. The IEEE Guide for Field Testing of Shielded Power Cable Systems Rated 5 kV and Above with Damped Alternating Current (DAC) Voltage, has been available for the past 7 years [3, 16]. Advanced DAC technology utilizes voltage testing in combination with non-destructive diagnostic methods, such as partial discharge (PD) detection and dissipation factor (tan δ) measurement of the cable system and associated accessories.
