Manual source-changeover system

This is the most simple type. It is controlled manually by an operator and

consequently the time required to switch from the normal to the replacement source

can vary.

A manual source-changeover system is made up of two or three mechanically

interlocked manually-operated circuit breakers or switch-disconnectors.

Remote-operated source-changeover system

This is the most commonly employed system for devices with high ratings

(above 400 A). No human intervention is required. Transfer from the normal to

the replacement source is controlled electrically.

A remote-controlled source-changeover system is made up of two or three circuit

breakers or switch-disconnectors linked by an electrical interlocking system that may

have different congurations. In addition, a mechanical interlocking system protects

against electrical malfunctions or incorrect manual operations.

Automatic source-changeover systems

An automatic controller may be added to a remote-operated source-changeover

system for automatic source control according to programmable operating modes.

This solution ensures optimum energy management:

transfer to a replacement source according to external requirements

management of power sources

regulation

emergency source replacement, etc.

The automatic controller may be tted with an option for communication with a

supervisor.
