Investigations on a combined resonance/VLF HV test system – partial discharge (PD) characteristics at VLF and DAC voltages
The necessity of HV cable testing is a given fact. So far, two testing methods, 24 hour soak or resonance testing are commonly used. This paper describes a comparison of test power demand dependent from voltage shape and test capacitance as well as the power consumption of test systems for different test techniques.

Frequency to temperature domain of transformer liquid insulation
The dielectric response of the overall transformer insulation is an invaluable source of information for those involved in the manufacture, operation and maintenance of power and distribution transformers. One of the greatest advances in the use of the transformer insulation dielectric response is without a doubt the possibility of performing advanced diagnostics of the oil-paper insulation to determine the moisture concentration of the solid insulation and the quality of the liquid insulation.
