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 …

Cheatsheet for calculating lightning surge arrester ratings

Are you sizing a lightning surge arrester for installation inside a substation? Electrical parameters: MCOV, TOV, and discharge voltage; should be on top of your list – for the correct application. If you are familiar with these parameters, then check out the below infographic, showing how to pick their values.
