The laboratory serves for scientific research purposes and for teaching undergraduate and engineering students at the Department of Electrical Power Engineering. The laboratory studies the effect of thermal aging on the electrical insulation properties of liquid dielectrics and the combined oil-paper insulation system. The laboratory is equipped with instruments that can be used to study the effect of the polarity of the supply voltage on the value of the flashover voltage in air, the effect of the interelectrode distance and the shape of the corona electrode on the course of the corona current and on the distribution of the space charge arising in the process of corona discharges. Other instruments are used to measure the electrical breakdown strength of liquid dielectrics and impregnated paper insulation, to measure the dielectric properties (permittivity and loss factor tgδ) of insulating oils depending on temperature and voltage, and to measure the wetting of liquid dielectrics.
