Switchgear/Breaker – Manager
Switchgear/Breaker – Manager
WARNING Misconfiguration of the switchgear can result in death or serious
injury.
Beside protection functions, protective relays more and more will take care about controlling switchgear, like circuit
breakers, load break switches, disconnectors and ground connectors.
The Switchgear/Breaker-Manager of this protective device is designed to manage one switchgear.
The correct configuration is an indispensable precondition for the proper functioning of the protective device. This
also is the case, when the switchgear is not controlled, but supervised only.
Single Line Diagram
The single line diagram includes the graphically description of the switchgear and its designation (name) as well as
its features (short circuit proof or not ...). For displaying in the devices software, the switchgear' designations (e. g.
QA1, QA2, instead of SG[x]) will be taken from the single line diagram (configuration file).
The configuration file includes the single line diagram and the switchgear properties. Switchgear properties and
single line diagram are coupled via the configuration file.
Switchgear Configuration
Wiring
At first the switchgears' positioning indicators have to be connected to the digital inputs of the protection device.
One of the position indicators (either the »Aux ON
« or the »Aux OFF«) contact has to be connected necessarily. It
is recommended to connect both contacts.
Thereafter the command outputs (relay outputs) have to be connected with the switchgear.
Please observe the following option: In the general settings of a circuit breaker, the
ON/OFF commands of a protection element can be issued to the same output relays,
where the other control commands are issued.
If the commands are issued to different relays output relays the amount of wiring
increases.
