Abstract:
The availability of electrical power from utility sometimes
disturbed, be it from internal of the system like equipment failure or
from external of the system like nature phenomenon, so it will obstruct
daily activities. However if the activities are urgent, so disturbance of
electrical power is not allowed. It cannot help but must use backup
supply that generally obtained from diesel generator that usually called
genset. Despite that, turning the genset on manually there will be a
rather long time delay so it is not too effective if the activities need to
handled fast. Therefore this research is useful to solve that problem. This
device uses three modes, those are Manual PLN, Manual Genset, and
Auto. Manual PLN and Manual Genset mode, the transfer of electricity
supply done manually. Meanwhile Auto mode transfers electricity
supply by detects which supply available and then transfer it to load.
The detection done by converting PLN’s AC supply to DC then
directing it to Arduino microcontroller which will process incoming
input then triggers TRIAC PLN or TRIAC Genset based on the status of
PLN’s supply so power will flow to load pass through the TRIAC. This
device can do the switching with good timing accuracy that matches
with the programmed delay in microcontroller with nominal current 6A.
