Purchase of the delivery of three (3) 550 kV Circuit breaker sets for outdoor installation at substation Bjæverskov (BJS).

The circuit breakers are used for switching the AC-filters on/off for the HVDC-connection to Germany (KONTEK). The circuit breaker system has interoperability with the pole control system.

Purchase of the delivery of three (3) 550 kV Circuit breaker sets for outdoor installation at substation Bjæverskov (BJS).

The circuit breakers are used for switching the AC-filters on/off for the HVDC-connection to Germany (KONTEK). The circuit breaker system has interoperability with the pole control system.

The circuit breakers must be fully compatible with all control and protection functionalities in KONTEK’s MACH-3 system. Incompatible circuit breakers would possibly entail non-scheduled outage time, additions/changes to unique adjustments, increased operating costs etc. Further, it is important, that KONTEK remain operational throughout the whole of the replacement period. If KONTEK were to be inoperational, beyond the scheduled outage time, due to the replacement of the circuit breaker sets, then that would incur severe economic cost.
