WebbThe method of distance protection scheme used was a three-stepped distance protection scheme in which the transmission line was segmented into three zones; 70%, 90% and 100% and the discrimination between each zone was 200ms in order to ensure proper coordination of the protective devices. WebbThere are three basic pilot cable protection relay schemes, current differential, phase ... In directional comparison scheme, the negative-sequence directional comparison, zero-sequence-based, and distance protection scheme are proposed respectively in Ref. [4][5][6]. Figure 5.

WebbThe Zone 1 elements of the distance relay have two settings. One is set to cover 80% of the protected line length as in the basic distance scheme. The other, known as ‘Extended Zone 1’or ‘Z1X’, is set to overreach the protected line, a setting of 120% of the protected line … WebbDistance protection scheme is preferred over graded lime-lag over-current protection in HV and EHV lines because A.
