Abstract: Modern on-site testing and diagnosis of transmission power cables up to 230kV consists of voltage testing, partial discharge detection and dissipation factor measurements. Applying AC voltages for this purpose has become in last year a common use. In addition to continuous AC energizing more and more the use of damped AC energizing is getting worldwide attention. In this paper, the use of modem technological solutions in power electronics and signal processing as well as in technical design and productionmethods will be discussed on the basis of damped AC systems up to 350 KV.
