Thhe probable reasons of low volage in houses are:
a)One of the phase on HT syde of transformer disconnected
because of breaking of jumper/HT fuse
b) excessive load on that particulr phase to which house is
conected
c)lower size of LT cable/ OH conductor selection resulting
in high voltage drop

Both generator parallel condition shared load equally but one genrator taking ampere more than the other what are all the causes to make like this
