"What to Do After the Warning of an On-line Insulation Diagnostic System? Off-line PD Monitoring with HVAC Testing!"
by Kubler, B.; Hauschild, W,
in the Proceedings of the 2004 Power Systems Conference and Exposition, 10-13 Oct. 2004, vol. 2, pp. 822 - 828The paper considers the relation between on-line monitoring and diagnostics on the one hand and high-voltage (HV) withstand and partial discharge (PD) on-site testing on the other. HV testing supplies the basic data (fingerprints) for diagnostics. In case of warnings by on-line diagnostic systems, off-line withstand and PD testing delivers the best possible information about defects and enables the classification of the risk. Because alternating voltage (AC) is the most important test voltage, the AC generation on site is considered. Frequency tuned resonant (ACRF) test systems are best adapted to on-site conditions. They can be simply combined with PD measuring equipment. The available ACRF test systems and their application to electric power equipment -from cable systems to power transformers - is described.
