Research of the Remote Fault Location Algorithm Based on Sampled Values for Measured Primary Electrical Quantities

Abstract

Digital current and voltage transformers are designed to large-scale transformation of voltage, alternating and/or direct current. Then they transmit the results of transformation to electricity metering systems, devices for measuring, relay protection, automatics, alarm, and control.There was developed the remote fault location method using data (instantaneous values of primary quantities) from innovative current and voltage sensors, which are included in the digital transformer structure. The results of the research of algorithm performance in cases of the influence of different distorting factors are presented.
