Electrical Schematics (Industrial Controls) is a basic course to start learning how to read, understand & design electrical schematics or electrical drawing (power and control circuits). We have covered various concepts that are required to design schematics. We start with very basics and eventually build on it.

We are also thrilled to share that this course has earned the high ranking of 9.4/10 by CourseMarks and ranks in the TOP 4% of 94,680 courses!

Some of the topics that you will come across are:

1) Basic details on schematics - What is schematic ? Where is it used ? Why is it needed?

2) Reading & Understanding Schematic - Title block, Disclaimer, Template, Designations, Cross-referencing, Legends etc.

3) Electrical Symbols & Switchgears - Electrical Symbols along with definition & images. Key technical details about switchgear like circuit  breakers, Contactors Isolators, Meters , Indicators & Protection devices

          a) Learn Off load & On Load devices

          b) Difference between isolators & circuit breakers

          c) NO & NC contacts

          d) Power & Auxiliary Contactor - contact numbering, advantages & limitations etc.

          e) Instrument Transformers

          f) Protection Devices

4) Designing circuit - in a step by step method - DOL Motor Starter Circuit

  • Control of motors - Star / Stop, Trip

  • Hold-on Contact

  • Indication circuits

  • Local remote

  • Auto manual operations

5) Basics of electrical interlocking

6) Basics of Metering Circuits

7) Application in Switchboards and practice questions.
