Abstract

The aim of the research was to receive the method of remote phasing of energetic objects using the vector transfer in the form of a digital signal by a longitudinal differential lines protection, which are working using fiber-optic line communications. A necessity of a method development appeared due to a situations, when on a new energetics objects there was no voltage, which makes possible to do the comparison while phasing. The development method was successfully tested in a laboratory conditions and also in process of facility commissioning of switchgear on OJSC “TANECO” and load-center substation on OJSC “Ammonium”.
