How Does a Generator Work?

In the event of a power outage, an automatic standby generator system will continue to power to your home in a seamless operation. This makes standby generators ideal for families with small children and those that depend on electric-powered medical equipment.

An automatic standby generator monitors the incoming voltage to your house around the clock. The controller in the generator does this through the automatic transfer switch (ATS), which can detect a power outage. If the utility power fails or drops below an acceptable level, the controller sends a signal to start the generator.

The ATS is the middleman – it simultaneously closes the utility line and opens the power line from your standby generator. The generator system supplies electricity to your home to provide convenience, comfort and security. Meanwhile, the controller keeps an eye on the utility power until it is restored.

As soon as the utility line voltage returns at a steady rate, the controller will sense this and then automatically disconnect the generator and transfer back to utility power. The generator continues to run for another minute or so to allow the engine to cool down, and then turns off and resets to standby mode. At the same time, the controller goes back to monitoring the lines for the next power outage.

An automatic standby generator has major advantages over a portable system – it has an automatic start, more power, lower running costs and all-weather operation. If your house suddenly loses power, the standby system will resume the electrical supply in a matter of seconds. Protect your family and your home from emergency power situations.
