Transfer admittance and unit-length parameters broadband measurement method and short-circuit fault substation

Research substation transient electromagnetic environment electromagnetic coupling problems secondary cable has an extremely important theoretical significance and practical value. In this paper, the National Outstanding Youth Science Fund Project "EMI coupling mechanism," focuses on the transfer impedance of shielded cable,  mcb circuit breaker  and unit-length parameters broadband measurement methods and substation system short circuit fault, lightning and switching operation on the secondary  Circuit breaker  electromagnetic coupling mechanism, through the measurement results and other literature comparing the calculated results to verify the measurement methods and calculation methods herein correctness. A new measurement shielded cable transfer impedance and transfer admittance easy way.
