A transfer switch, either manual or automatic, is a legal requirement in every country when you install a diesel generator in any premises with a mains electricity supply. When the mains supply fails, the transfer switch is used to start the generator to take over where the mains left off. The purpose of an automatic transfer switch is to do the job automatically, which is much quicker than doing it by hand.
Now in some situations, a delay in restoring power to a building may not be very important. If you are at home watching Coronation Street, you may miss a little of it while someone goes to start the generator with a manual switch. However, in a hospital, a delay in restoring power could be a catastrophe and a matter of life and death.
The reason that a transfer switch is required by law is that it will prevent the mains power from coming into contact with the generator which would probably burn out if that happened, but more importantly, when the power is restored from the mains it prevents the generator from back feeding the mains when it has failed, which could endanger the lives of electricity workers trying to restore power.
When you want to buy an automatic transfer switch in the UK you should know that there are two types – those with mains detection and those without.
An automatic transfer switch with mains detection will monitor the mains supply and when it detects a failure will send a signal to the generator to start. When the generator is ready it will send a signal to the ATS informing it of this and the ATS will then switch to the generator.
If the ATS does not have mains detection, the system needs mains detection built into it somewhere else, normally the generator. When the generator detects a mains failure it will send a signal to the ATS telling it to disconnect from the mains and will then startup. When the generator is ready to connect it will send a signal to the ATS telling it to switch over.
