Determining the accuracy locating faults in a power-transmission line by an artificial short circuit method

Locking devices (LDs) and most recorders of emergency events and microprocessor protection terminals are provided with the capacity for fault location determination (FLD) of power transmission lines that are in the operating zone of the North Caucasus Manager Department. The analysis presented in th...
