The advantages of shield cable shield grounded at both ends
When the control cable for flux bus transient current generated by the layer will be induced, shielding current shielded cable, the flux is produced by the effect of shielding current, flux will link transient current offset the core cable. Assume that the shielding effect ideal, a combination of the two, will cause by the flux core cable shielding layer completely surrounded in zero, shielding layer formed an ideal Faraday cage. This is the same with two short circuited coil of transformer core flux in the ideal, will be zero. Of course, the shielding effect of shielding layer, due to various reasons, can not be completely ideal, therefore, is the core wire shielding in busbar transient current role, will still induces a certain voltage.
