Technical coordination
## Connection infrastructure is part of the project

Projects may require transformers, switchgear, lines, cables, protection and metering. The solution follows connection conditions and existing installations.

We document interfaces and testing. Voltage level, scope and responsibilities are specified for each project.

Work areas
## From the diagram to energisation

Work follows the design and applicable standards.

### Electrical concept

Power and connection scheme coordination.

### Engineering

Diagrams, plans and calculations.

### Transformation

Transformers and switchgear.

### Protection

Protection and automation settings.

### Lines and cables

Routes and connections.

### Testing

Verification and documented results.

Controlled delivery
## Verified equipment and connections

Operation and maintenance are considered during design.
