� Disconnectors shall not be opened or closed on-load

� Earthing switches shall not be closed onto voltage

� CB:s shall not be closed when surrounding disconnectors are in intermediate positions

� CB opening is only interlocked at a bus-coupler bay, if a busbar transfer is in progress

Basic principles - Interlocking

Installed to prevent maloperationsof disconnectors and earthing switches

Reservation

The purpose of the Reservation method is:

� To prevent simultaneous operation (manual operation)

� To ensure that interlocking information is correct at the time of operation
