What Is a Closed Transition Transfer Switch?

A big part of keeping any business productive, safe, and ultimately successful is in managing risks and planning for equipment and electrical conflicts. To fulfill this goal many businesses rely on generator power to keep systems operation in time of incident or power loss, safety switches to mitigate damage and physical harm, and accompanying accessories and compatible devices to keep things running as smooth as possible.

One major tool is a transfer switch—a device that governs access to an established permanent or whole-structure generator. But transfer switches come in many types, and each is usable in specific scenarios and for specific equipment. How do you know what to choose? Learn about each, of course, which is why PSI Control Solutions is here to talk about “closed transition” transfer switches!

What’s a Transfer Switch?

Putting it very simply, a transfer switch is a device that essentially acts as a transition for utility and generator power. When a transfer switch is installed all one needs to do in the event of an outage to access generator power is to simply switch the transfer switch on, and it will do the rest. In the event of an automatic switch the entire process is automated, giving you immediate access to electrical power with no interruption. A manual switch is also a quick and safe way to get power, but does require manually engaging the device.

What Does Closed Transition Mean?

Closed transition is one of a few terms used to describe various transfer switch applications and states. The differing factor between all transfer types is in the order that it makes and breaks connections, these being the connections to utility power and the connections to generator power.

In a closed transition transfer switch, the connection to generator power and utility power is held until a stable connection is established. Though very brief (less than a tenth of a second), this short term overlap of power sources eliminates electrical stuttering, making the transition of power much more seamless than “open” transition transfer switches.

What Benefits Does This Provide?

The “make before break” connection method sees a lot of use in industries that cannot safely tolerate any loss of electrical power, which typically extends to data centers, medical facilities, manufacturers that utilize potentially dangerous equipment, etc.

Additionally closed transition switches are particularly useful in performing electrical safety tests and drills, since a closed transition system incorporated with your generator enables seamless transition from an electrical standpoint, which eliminates the downtime that often comes when testing.
