Based on the distributed parameter model for transmission line, a new fault location method for shortcircuit fault of two points on different phases of the power transmission line is presented.
Calculated book is the parameter, short-circuit current and protective to worth surely to carry out calculation.
计算书主要是对设计中的参数、短路电流及保护的整定值进行计算。

Two Solutions to the model equivalent parameter estimation are proposed, one based on the three-phase short-circuit capacity, this method works with good computational speed, but accuracy is not high;
