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.
3304what is the safe meggar values for motor, transformer HT, LT and Cables? IF we want to replace I/C bay at our 220 kv substation which is of 140 mw load capacity bay to be replaced by 400 mw capacity bay.other than CT(1200/1) what are the other equipment i have to replace. why we generally use 3.5 core cable or in other word 1/2 core for neutral and also confirm me that in balance conditiob(3 phase)current in neutral will zero
2217In LT Line What is the minimum clearance required between phase to phase busbar & between Phase to body of the panel? Also between Neutral &phase, & Neutral & body of panel. as per standards.
