MV switchgear
The station is always equipped with ABB SafeRing MV switchgear. Type CV is used as the
standard and consists of two modules:
•
C uses a double cable bushing configuration to connect to:
1.
The grid-side module with grid cable terminals and a disconnecting and earthing
switch. See figure below.
2.
The connection of other parallel-connected substations.
•
V is the Vacuum circuit breaker module equipped with the Self power relay (REJ 603)
as a standard.
MV switchgear circuit
The diagrams below show the standard CV MV switchgear and optional CCV MV switchgear.
Both the switchgears can be upgraded to V-module motorized and REF615 protection relay
by adding combisensors for metering purpose.
For more information, see MV switchgear manuals (
and 1VDD006116).
