In this paper

intelligent component terminal disturbance voltages are measured while the circuit breaker closing and O-C-O operation in a 500 k V GIS substation

GIS shell ground potential rise. GIS equipment operation of circuit breaker intelligent component port on the electromagnetic disturbance characteristics is studied. The results show that the circuit breaker closing the station ground potential rise value maximum of not more than 2 300 V

but the O-C-O operation is nearly 5 000 V; the maximum common mode disturbance voltage on the ports of TA in control cabinets is less than 250 V. The rising edge of micro pulse disturbance voltage in intelligent component ports is very steep

between 3.2 and 6.8 ns

less than test results of previous research.The main frequency amplitude of disturbance voltage of the station is higher than the preliminary experimental results.
