The generator operating system automatically uses a motorized change over switch devices

Abstract

Abstract This system is carried out using two power between the National Electricity Company (PLN) as the main power and the generator as backup power. This system uses 30KVA power capacity for PLN and 45KVA for generator set (genset). This system relies heavily on the crucial role of the motorized change over switch device because the automatic transfer system can run properly without collisions when using the backup power supply and when the main power supplies return. The results provided by the observations on two power experiments between the power of the PLN and the power of the generator when there is a blackout at the PLN. The automatically performance of motorized change over switch works has a range of pauses of 18 seconds to be able to power the genset capable of taking on the role of PLN to back up the Building. Furthermore, when the PLN power returns the power is held for 30 seconds by a motorized change the over switch. It ensures that the main power of the PLN reconnected.
