# Electrical Schematics (Industrial Controls)

Learn to read, understand and design electrical schematics / electrical wiring drawings!!

Electrical Schematics (Industrial Controls) is a basic course to start learning 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.

What you’ll learn

• How to read, understand & design schematics.
• Concept of power and control circuits.
• Designing a circuit from scratch : Starter Circuits.
• Indication circuits.
• Local Remote & Auto Manual Operation.
• Basics of electrical interlocking.
• Metering circuits.
• Learn certain key switchgears.
• Electrical symbols.
• Cross-referencing and Designations in Schematics.
• Starter Circuit.
• Concept of NO & NC contacts.
• Contactor’s Contact Numbering.

Course Content

• Introduction and Concept Building –> 9 lectures • 26min.
• Section 2 : Key Switchgears –> 7 lectures • 25min.
• Section 3 : Designing of Schematics –> 18 lectures • 1hr 19min.
• Section 4 : Basic of Interlocking –> 2 lectures • 11min.
• Section 5: Metering Circuits –> 3 lectures • 11min.
• Section 6 : Application of Schematics and Quick course recap –> 2 lectures • 5min.

Requirements

• Should have a basic degree or knowledge in Electrical Engineering – B tech, B.E., Diploma or any similar relevant educational background.

Electrical Schematics (Industrial Controls) is a basic course to start learning 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.

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) 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 Contacts – contact numbering etc.

e) Instrument Transformers

4) Designing circuit – in a step by step method – Control of motors, indication circuits, Local remote and auto manual operations & metering    circuits: Starter Circuit

5) Basics of electrical interlocking

6) Basics of Metering Circuits

7) Application in Switchboards and practice questions.
