Course Description

Welcome to the course dedicated to the design and analysis of an AC Distribution Panel (ACDB) and its components and proper schematics analysis. You will learn how to successfully read and analyze ACDB’s single-line diagrams, wirings, and interlocking schematics.

AC Distribution Panel (ACDB) is one of the most important panel type in power substations, power plants and factories.

AC Distribution Panel explained in this course has two incomers (two sources), where one power supply is fed through the auxiliary transformer, and the other is fed through the Generator. Interlocking is provided between incomers and the coupler. The course explains a single-line diagram, interlock logic, interlocking schematic, and wiring functionality. Normally open and closed concepts are also presented.

Finally, you can find schematics drawing for self-study.
