Abstract

With an on-site voltage test it is possible to evaluate polymer insulated cables after laying, repairing or some years in operation. The on-site cable testing can be done easily with frequency tuned series resonant test sets which are still available for testing of medium and high voltage cables. Some tested cables failed after a short time in operation although they had passed the previous voltage test without breakdown. A combination of the voltage test with an additional partial discharge (PD) measurement can increase the test efficiency, but the on-site PD measurement has a lot of difficulties caused by ambient noise. The paper describes results of on-site medium voltage cable testing with a frequency tuned resonant test set and an additional PD measurement with a special PD measuring system.
