Is it possible to connect a single-phase generator to a three-phase network?
Good evening, I am interested in the following question: I have three phases at the entrance to my private house, then all consumers are distributed in phases, for a uniform load. I want to buy a single-phase diesel generator with which the complete ABP comes. Is it possible to connect a single-phase ATS to a three-phase switchboard, if initially this ATS comes complete with a single-phase generator? I found information on how to connect the generator to a three-phase ATS and understood its connection principle, but what about the ATS that goes to a single-phase generator, or are they the same (one phase and three phases)?

Hello! ATS performs automatic recovery of consumer power by switching to a backup network. If you have a single-phase generator, then a single-phase ATS will switch the load power between the generator power and the mains. A three-phase generator is a three-phase source of electricity, the ATS in this case will switch the power between two three-phase sources of electricity - three phases of the mains and three phases of the generator.
If you have a single-phase generator, then you have one phase available. That is, if you want to connect a three-phase ATS, then just one phase from the generator is connected to the three phases and thus, when the ATS is triggered, the generator feeds the total load of your consumers. That is, in fact, you put all your load, which is divided into three phases, into one phase of the generator. This option allows you to power only single-phase consumers. If there is a need to power three-phase loads, then for this purpose you need a three-phase voltage source - a three-phase generator.
