摘要： A one-terminal process for locating a fault associated with a transmission system is disclosed. The process is based on the principle fault sequence can be determined by a distribution factor in positive faults may be any defect among phases or ground. The process begins by one end of a transmission line. If the data is oscillographic data, measured data is in phasor form, or after phasors have been calculated determined. Thereafter, a decision is made whether the pre-fault data data is sound, an equation is selected to calculate the fault location decision is made whether the phase is a three-phase fault. Then, a employed to compensate for the fault through a resistance by measuring part of the apparent line impedance. If the fault is not a three-phase formula is not employed and the appropriate equation is selected for the fault location parameter. Accurate fault location techniques for also disclose. The system is insensitive to the zero sequence current information about the system source impedances is required.
