￭ MV switchgear
The MVS is always equipped with outdoor 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.
