This lesson is an overview for the topics which will be covered in this course.

Overview (in Hindi)

This lesson talks about the elementary basics of magnetic circuits like magnetic flux, magnetic field, permeability, reluctance, permeance. Then it compares magnetic circuit with electric circuit.

Basics of Magnetic Circuits - Part 1 (in Hindi)

This lesson briefly describes the elementary basics of magnetic circuits like Faraday's Law, Lenz's law, changes in flux linkage, self inductance and mutual inductance.

Basics of Magnetic Circuits - Part 2 (in Hindi)

This lesson introduces transformer with its definition, general categorization and some other basic types of  transformers.

Introduction to Transformer (in Hindi)

This lesson describes the working of a transformer. It gives a brief about the ideal transformer, practical transformer, phasor diagrams and the equivalent circuit of transformer.

Operating Principle and Equivalent Circuit of Transformer (in Hindi)

This lesson gives a brief description about the voltage regulation and its need. Also it tells us about the condition for zero and maximum voltage regulation with some practice questions as well.

Voltage Regulation of Transformer (in Hindi)

This lesson briefs about the transformer losses. About the core loss, copper loss, dielectric and stray load loss. Also some practice questions are there to make the concept more clear.

Transformer Losses (in Hindi)

This lesson describes the various test conducted on the transformer. About the open circuit test, short circuit test, shumpner's test. About the transformer efficiency and some practice questions as well.

Tests Conducted and Transformer Efficiency (in Hindi)

This lesson discusses about the parallel operation of transformers, it's necessity, it's equivalent circuit and some major conclusions. Also at last it tells the applications of transformer with some practice questions.
This lessons ends the course Electrical Machinery Part - 1 (Transformer)

Parallel Operation of Transformers (in Hindi)

This lesson describes the auto-transformers and it's equivalent circuit. The characteristics of auto-transformer and the comparison between 2 winding transformer and auto-transformers is also discussed.

Ravendra Yadav

In this course we will be discussing about the properties of transformer core, laminations of core, magnetostriction and core type and shell type transformer.

(Hindi) Transformer for IES : Part - 2

This is the Crash course on transformer for RVUNL JE EXAM so all the topics of transformers will be covered in short not in detail.

Crash Course on Transformers for RVUNL JE EXAM (29/07/2019)

In this very new crash course we will be discussing about the synchronous machines. we will cover all the important topics for the subject which is also be important for last minute revision and preperation to.

Crash course on synchronous machines for all JE EXAMS

This course is very important for ESE aspirants.

(Hindi) Torque developed and Commutation in DC Motor

In this course we will be discussing about each and every topic of DC machines in brief which will prove very helpful for the students for last minute preperation or for revision point of view.
