Joint workplace VSD a.s. and FEI TUKE in ES Lemešany
Contact persons:
- Ing. Jozef Baran, VSD, a.s.
- prof. Ing. Iraida Kolcunová, PhD., KEE FEI TUKE
The HV test room is located in the premises of the Lemešany substation. It is a joint property of TUKE and VSD. The Department of Electrical Power Engineering uses a testing laboratory 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 electrical distribution networks. The test room examines the electrical insulating properties of high-voltage power equipment: HV transformer bushings, HV and VHV insulator hinges contaminated with industrial exhausts, surge arresters, HV and VHV circuit breakers, HV cables and cable assemblies. Tests are performed: withstand voltage, measurement of the degree of pollution of insulators, measurement of switching characteristics, measurement of the level of partial discharges, measurement of capacity and loss factor, measurement of the quality of current connections, measurement of the degree of water absorption of insulation systems.
