What is Star and Delta Connection?
In electrical circuit analysis there are certain type of complex circuits that have resistances connected in either series or parallel. These complex arrangements are usually connected in the T, Y, Delta or pi connections. Among these star and delta are some common types of connection.
Star Connection Circuit
Star connection circuit is the circuit where the three resistor in the circuit have a common point. The shape of the circuit can be in the shape of ‘Y’ and ‘T’ alphabet or we say star shape. The common point is grounded in most cases. This type of connections are required when there is need for a neutral point. It is mostly used in low and medium voltage distribution systems.
Delta Connection Circuit
Delta connection is the type of connection where the three resistors are connected in a such way that they form a loop and they every two resistors have a common node. It is sometimes also in the shape of pi and mostly in shape of a triangle or can be referred to as delta. there is no common or neutral point available in the system. This connection type is used in high voltage transmission system.
Star to Delta Conversion
In this article we will discuss about star to delta conversion. We will first discuss about star and delta connections, current and voltage equations in these circuits. Then we will discuss about the differences between the star and delta connection. We will also discuss in detail the steps followed to derive the equations for conversion. In addition to this we will look into some solved examples that will help us understand the concept better. Later in the article we will discuss about the applications, advantages and disadvantages of this conversion.
