# UNDERSTANDING TRANSFORMER SCHEMATICS

Three Phase Transformer Connections and Basics
The standard method for marking three phase transformer windings is to label the three primary windings with capital (upper case) letters A, B and C, used to represent the three individual phases of RED,  YELLOW  and BLUE. The secondary windings are labelled with small (lower case) letters a, b
Transformer Basics and Transformer Principles
The Voltage Transformer can be thought of as an electrical component rather than an electronic component. A transformer basically is very simple static (or stationary) electro-magnetic passive electrical device that works on the principle of Faraday’s law of induction by converting electrical energy from one value to another.Transformer Construction · Three Phase Transformer · 3.

How to Read a Schematic - learnkfun
The most fundamental of circuit components and symbols! Resistors on a schematic are usually represented by a few zig-zag lines, with two terminals extending outward. Schematics using international symbols may instead use a featureless rectangle, instead of the squiggles. Potentiometers and Variable Resistors
Easy understanding of 3-phase transformer connections
Easy understanding of 3-phase transformer connections - Delta–Delta, Wye–Wye, Delta–Wye and Wye–Delta (on photo: Jefferson Electric transformer) The schematic diagram at the upper right is perhaps easier to analyze, as the delta connections can clearly be seen.
