Process
Building a new substation or retrofitting an existing one is a complex process. The main steps in substation design and engineering are as follows:
- Selection of switching system (ring bus, breaker-and-a-half, etc.)
- Preparation of key plan showing location of all components
- Equipment selection and ordering
- Engineering support for NOC, licensing and approvals
- Civil and structural works
- Equipment erection and installation
- Protection relay setting and testing
- Testing and commissioning
