What is the reason for low voltage in houses?

Answer Posted / anand

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

I have made a 3 phase thyristor full bridge rectifier. But at the moment it is working only for the half bridge operation. Both the half bridges are on operation separately but when i put it into full bridge operation the oscilloscope output is zero. I rechecked that the pulses are correct for each thyristor. what could be the possible reason for this?
