The VHV test room is located in the premises of the Lemešany substation. It is the joint property of TUKE and VSD. The Department of Electrical Power Engineering uses the test room for the purposes of higher education and the development of creative scientific research. VSD employees are engaged in testing elements used for the construction of transmission and distribution power distribution networks. The test room is used to investigate the electrical insulation properties of high-voltage electrical power equipment: VHV transformer bushings, HV and VHV insulator hangers contaminated with industrial exhaust fumes, surge arresters, HV and VHV circuit breakers, HV cables and cable assemblies. The following tests are performed: withstand voltage, measurement of the degree of contamination of insulators, measurement of switching characteristics, measurement of the level of partial discharges, measurement of capacitance and loss factor, measurement of the quality of current connections, measurement of the degree of water absorption of insulation systems.
