Incon OPTImizer 2 - Figure 5: Breaker Cabinet and Control House Interface; General Planning Considerations

General Planning Considerations
The OPTImizer
2
may be installed in a control house or breaker cabinet. The required interfaces can be obtained at either
location. The SF
6
sensors must be installed on the circuit breaker itself. Sensor accuracy is best when installed nearest to
the interrupter vessel.
The OPTImizer
2
should be installed as close to the CT Pickup Coils as possible. Cut any excess cable from the Pickup
Coils. It is not recommended to extend the Pickup Coil cables.
