Substation engineering

Pre-bid and post-bid engineering for AIS and GIS substations up to 765 kV.

The engineering challenge

A clear basis.
A coordinated design.

Substation engineering connects electrical clearances, protection, equipment and the structures around them. We provide pre-bid and post-bid consultancy for AIS and GIS substations up to 765 kV, coordinating the electrical, structural and civil design packages around the project brief.

Where we contribute

Support through the details.

The scope is agreed around your project stage and available inputs.

Layouts and electrical clearances

Plan and section layouts for AIS and GIS substations, with electrical clearances coordinated across equipment, structures and access requirements.

Earthing, lightning and illumination

Earth-mat design and calculations, direct-stroke lightning protection, and illumination design with the associated drawings.

Equipment and erection documentation

Equipment specifications, cable schedules and erection material requirements, including clamps and connectors.

Protection and equipment checks

Relay settings and coordination, current-transformer sizing and short-circuit force calculations based on the project’s electrical inputs.

Civil and structural packages

Main structures, equipment supports and transformer foundations, with roads, culverts, drains, gates and fencing. GIS and control-room design can include trenches, panel placement and internal electrification.

A defined scope of work

From inputs
to useful outputs.

We confirm the required calculations, drawings and review support at the start of each engagement.
