Three set (each phase contain 2 cable of 400 mmsq CU XLPE
AWA) of single core cables are connected to 11 KV motor of
14 MW & the switch gear supplay is taken from 11kv feeder &
this supplay taken from 275 KV substation. Problem is one
pair cable(L3- 2 cable ) getting very hot & gland melted
and damaged in switch gear side. the other two cable
haven't any more hot(ambient temp only & L3 haveing 95- 100
Degree C. The same problem happened in 275 KV substation
switch gear side also where the supply taken for 11 kv
switch gear. But here L2 phese cable had problem. Why it is
happening like this?. The cable having temperature
different at different location from gland side inthe case
of 11KV feeder of 275 kv substation. why ?
