Abstract:The multi-conductor transmission line(MTL) theory was used in the analysis of the coupling between telecommunication cable and external field,the finite-difference time domain(FDTD) method was used to simulate the transient response.According to the results of induced voltages and currents,an approximate single-wire line model replaced the multi-conductor transmission line model and the corresponding electric parameters were calculated in term of the singlewire line model.The result indicates that agreement had been achieved with other method.The effects on induced voltages with simplified single-wire line caused by cable length,electric parameters of the ground and terminated impedance are examined and the results are discussed.
Keywords:multi-conductor transmission line  finite-difference time domain  external field  cable  induced voltage
