Sažetak
The paper describes problems with electromagnetic compatibility (EMC) of the secondary equipment in the 123 kV gas insulated switchgear (GIS). The causes for malfunc-tioning of the busbar protection during disconnector switch-ing 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 transients had lower magnitudes than allowed, they caused malfunction-ing of the secondary equipment, e.g. busbar protection. Con-tinuous monitoring of the HV equipment's influence on the secondary equipment and implementation of some precau-tionary protection measures are recommended.
