Question

I use ATS to shift from generator A to Generator B with out disturbing the operation.If this is possible, please give me the specs.I use 2 - 700kva volvo generators

Answer 1

It depends what you are trying to do?

First do you want to use the second generator as a spare or should it be stand by?Ä°f the load is not more than 50% of the capacity it is ok. But in any case the sensitivity of the tranfer swich is very important. There will be an interruption during the transfer even for a 1/sec (reaction time for the switch )Auto transfer switch senses the low voltage from the relay and than it reacts as  follows "shut down the normal energy in this case it is the gen1 and then it starts gen2 and than gives the energy to the bus bar." That means there will be an interruption.The  other case  is more complicated we use sencronisation system same as we use in hydroelectric or thermal power plants.But it will cost alot of money.
