Today, in the 5th part of his tutorial, Nasir studies the working and advantages of an Open Transition Transfer switch. Let’s check what he has to teach!


Open transition transfer switches are designed to switch between the normally present power supply; which is being supplied to our homes by the power stations, and the backup arrangement in the form of some generator or anything.

They operate between these two supplies depending upon the conditions, if the primary power supply is available or not.

They have a switch which monitors the power sources and keeps a check so that whenever the primary source fails to deliver the power, it immediately switches to the backup set of generators.

But the major difference that it has from the closed transition transfer switch is that, this switching is not performed immediately, instead there is a short break between the opening of one contact and the closing of the other.
