Answer Posted / raul
the batteries in a station are floated onto the dc bus bars
with the help of float charger i.e. all the dc requirements
r being made with the help of float charger and not by the
battery itself which is done by keeping the float charger
voltage a few volts higher than d battery voltage........in
addition to provide d.c. requirements in a
station .......the float charger provides additional few
hundreds of amperes to the battery to compensate for the
losses in d capacity of the battery due to local action
among the plates of the battery........that is why it is
also called as TRICKLE charger......in case of a.c. failure
in station, battery comes in to play and the battery starts
getting discharged........so in order to keep the battery
charged at its rated values, boost charger comes into play
and charges the battery...........and after the restoration
of the a.c. supply to the station, it is again floated onto
the d.c. bus bars with the help of FLOAT charger........
