Coordinated protection
The coordination study and the relay settings come with the supply, verified on a simulator.
Medium and high voltage
HV-138 Bay
Pre-assembled 138 kV line bay
Description
A complete line bay — steelwork, switchgear, protection and earthing — delivered as a single supply with engineering and coordination included.
Buying a bay in pieces means somebody has to integrate it, and that somebody ends up being the client. Here the protection coordination arrives with the equipment.

What sets this unit apart
Structure calculated for the site
Wind, seismic and the local pollution level go into the calculation, not a generic case.
Installed while the substation stays live
The sequence is planned so the outage is limited to the final connection.
Telecontrol ready
Integration with the dispatch centre tested at works against the client's own protocol.
