Research on Disturbance Voltage of Secondary Cables Due to a Circuit Breaker Ground Fault in UHVDC Convertor Substation
To analyze disturbance voltage of secondary cables due to a circuit breaker ground fault in UHVDC convertor substation, this paper established an equivalent model according to the real size of ground grid as well as secondary cable, and carried out spot-measuring. For the purpose of suppressing interference on cores caused by ground potential rising, it's better to ensure armor grounded in both ends, meanwhile, to make shielding sheath grounded only in sensitive devices.
