Switchboards

The switchboard is the node where the supply, distribution and protection of the whole site come together. We prepare the documentation for its manufacture and carry out its installation and connection on site.

Designing a board is not arranging devices in a cabinet. It starts with calculating the short-circuit current at every point, checking that the chosen switchgear withstands those currents thermally and dynamically, and setting the protection so that a fault trips only the affected feeder rather than the whole board. That is called selectivity, and it is the difference between one stopped consumer and stopped production.

We work with main distribution boards, floor and sub-distribution boards, control and automation panels, reactive power compensation panels and medium-voltage switchgear. The documentation includes single-line diagrams, secondary circuit diagrams, switchgear layout and full specifications.

In maintenance we carry out periodic servicing, thermographic surveys of terminations, checking and resetting of protection, and extension of existing boards with new feeders.
