Which standard we are following earthing resistance test
sourse is 66 KV / 350 MVA, transfarmer is 1000 KVA 6.6 / 0.415 kv, iF fault is 28.75 MVA on 0.415 KV Bus then calculat the Transfarmer Impidance
Minimum IR value of 1.1 kv grade 3.5c (300, 240,185,150,120,95,70,50,35,25) sqmm Aluminium XLPE cable and 4c (16, 10,6 & 4) sqmm cu arm cable between RY,YB,BR,RN,YN,BN,RE,YE,BE & NE.
