Substation Equipment

Power substations contain transformers, breakers, switches, and plenty other critical pieces. This category explains the equipment design in detail.

Practical Implementation of Transformer Winding Connections – 3 Critical Steps to Consider

To understand how transformer winding connections are made, in this article I will build a three-phase transformer delta-delta (with 180degree phase-shift) using three (3) single-phase transformers. Although this exercise seems moot for substation design, practical applications of single-phase transformers exist. For instance, as a station-service source. Also, to guide you step-by-step, I’ve prepared the below …
