Designing Additional Electrical Substation

The electrical infrastructure for a campus was designed to meet the increasing power demand while adhering to the State Electricity Board norms. 

The State stipulates that any consumer with a total demand nearing 3000 kVA must have a dedicated 11 kV supply to avoid overloading shared feeders and ensure stability. In this project, Substation 1 handles a load of around 1250 kVA with two 1000 kVA transformers, and Substation 2 manages a load of 1750 kVA with one existing 1000 kVA transformer and a new 1600 kVA transformer. The combined demand of these two substations is around 3000 kVA, which reaches the state threshold for requiring a dedicated 11 kV supply.

To ensure compliance with the State Electricity Board's requirement for a dedicated high-voltage supply when the demand exceeds 3000 kVA, we have proposed a third substation. This substation, equipped with two 1600 kVA transformers, will cater to 2500 kVA of new demand. Its introduction not only minimizes the risks of voltage fluctuations but also ensures future scalability and optimized power distribution across the campus, providing a robust and reliable solution.
