In 2016 SAIDI value in Pastel feeders amounted to 0,053 hours/year and SAIFI value amounted to 0,119 times/year. These values continue to increase until 2018. This was caused by excavation work. Whereas in Red feeders, the value of SAIDI and SAIFI is inconstant. In 2016 SAIDI and SAIFI values were amounted to 0,926 hours/year and 1,59 times/year. In 2017 the value of SAIDI and SAIFI in Red feeders decreased to 0,2112 hours/year and 0,318 times/year. This interference was caused by jointing cable. And in 2018 it increased again to 3,61 hours/year and 0,897 times/year. The calculation of SAIDI and SAIFI in this study uses per-component method calculation according to SPLN: 59 in 1985. SAIDI and SAIFI calculation in Pastel feeders produces values that are not in accordance with SPLN: 59 in 1986. And in Red feeders the value of SAIDI and SAIFI that in accordance with SPLN: 59 in 1986 in 2017.} }
