Automatic Changeover Switch Connection
Low voltage automatic transfer switch assemblies provide a reliable means of transferring critical load connections between primary and alternating electrical power sources.
Data centers, hospitals, factories, and many other types of facilities that require continuous or near-continuous operation time typically use a backup (alternating) power source such as a generator or backup power when their Normal (primary) power source becomes unavailable.
What TTY devices are available?
Various formulas are available, using two and three power sources.
Two power sources
Public service-generator
The standard transfer switch configuration includes electrical service and a generator for normal and emergency power sources. This system is generally referred to as the back-up generator system. The single generator shown can be made up of several generator sets operating in parallel.
Public service-public service
This use case uses two utility sources that provide redundancy in the distribution system and allow service to be quickly restored to the load in the event of an upstream equipment failure. The two sources can be independent of each other, requiring the utility to provide two electricity services, or they can come from a single electricity service, distributed through redundant channels to the within the facility.
Generator-generator
Transfer switches, sometimes, are applied between two generator sets for main power use, often in remote installations. In this case, the generator may be required to provide continuous power 24 hours a day, 7 days a week. To fairly share the operating time, the power source is periodically alternated between the generator sets.
