Sažetak
The paper describes problems with electromagnetic compatibility (EMC) of the secondary equipment in 121 kV gas-insulated switchgear (GIS). The causes for the malfunctioning of the busbar protection during disconnector switching have been studied. Thorough measurements and computer simulations were conducted in order to determine magnitudes and frequencies of the transient voltages and currents in the secondary circuits. Although, measured secondary overvoltages have had lower magnitudes than allowed, they caused malfunctioning of the secondary equipment, e.g. busbar protection. Continuos monitoring of the HV equipment influence on the secondary equipment and implementation of some precautionary protection measures are recommended.
