In the framework of elections in 2019, there could be short circuit caused due to interruption of the ground phase, phase to phase and three-phase at the feeder supply KPU building. Data from the short-circuit current GI / GITET in the 1st half of 2018 recorded their short circuit to ground single phase and three phase in GI Dukuh Atas of 24.922 and 25.909 kVA kVA. Voltage Dips causing much as 2047.884 V when one phase to ground disturbance and 7999.99 V when disturbances 3 phase. The disorder can be causes disruption of the election results of the data input process, the disruption of the meeting process,,Blinking disturbance voltage can be minimized impact by using UPS Online. Because the online UPS constantly work back up the load so it will not happen pulsating voltage.} }
