Circuits or systems in which the ac sources operate at the same frequency but different phases are known as polyphase. As distinct from a single-phase system, a three-phase system is produced by a generator consisting of three sources having the same amplitude and frequency but outof phase with each other by 120°. Since the three-phase system is by farthe most prevalent and most economical polyphase system, discussion inthis course is mainly on three-phase systems.

In this lesson, I will introduce you the definition of polyphase network, Types of polyphase networks and importance of 3-phase Networks.

Basics of Polyphase Networks

As a continuation of last lesson, we continue to discuss about generation of 3-phase voltages and also define aspects such as Phase sequence. And finally 3-phase loads are also introduced.

Basics of 3-phase Networks

As we now know that two different connections are possible for a 3-phase source and a 3-phase load. So 4 different topologies are ultimately possible for a 3-phase Power System. We in this lesson discuss two important combinations out of those 4.

3-Phase Sources and Loads - Connections

In this lesson we get familiar about most commonly asked type basic numericals in 3-phase Networks

Example Numericals

In this lesson we will be solving some innovatively framed interesting questions from previous GATE papers

Previous GATE questions: Part 1

In this lesson we deal an innovative GATE (EE) question which is a blend of 3 Phase Circuits and Network Theorems.

Rudrarup Sengupta

This course comprehensively covers all the previous years GATE questions om Basics of Semiconductor Physics from 2007 to 2018. All solutions are given orally so that the student may do the problems themselves. Concepts based on the problems are re-visited and revised. This course is typically designed for GATE 2019 aspirants.
