BATTERY INDICATION SYSTEM FOR GENERATOR SET

The standby generator is important in order to back up the main power supply failure.
The function of standby generator is crucial in order to maintain the capability of equipment
and devices operation. When main failure occurs, the system will switch from main to
standby generator to get the power supply. The start-up of generator set will use batteries for
engine cranking. The batteries will be used as supplied power to starter motor to give initial
move to engine flywheel. Batteries are used to power up the starter motor to rotate the engine
flywheel. Without batteries, the electric starter motor cannot be used, thus generator set
cannot be start up. The aim of this project is to build a system to identifY undervolatage and
overvoltage at battery used in generator set. The system then will give indication upon the
detected voltage limit. This system will reduce the failure of generator to start as backup
while there is no main power supply. This project will use Direct Current (DC) voltage sensor
to determine the low and high voltage present during battery charging and the battery voltage
itself.
