Answers
Explanation:
of three branches can be done in different forms however most commonly used methods are star connection otherwise delta connection. A star connection can be defined as the three branches of a network can be commonly connected to a mutual point in Y -model. Similarly, a delta connection can be defined as; the three branches of a network are connected in a closed loop in the delta model. But, these connections can be changed from one model to another model. These two conversions are mainly used to make simpler of complex networks. This article discusses an overview of the star to delta conversion as well as a delta to star connection.
Star to Delta Conversion and Delta to Star Conversion
The typical three-phase networks use two main methods by names which specify the way in which resistances are allied. In a star connection of the network, the circuit can be connected in symbol ‘∆’ model, similarly in a delta connection of the network; the circuit can be connected in symbol ‘∆’. We know that we can change the T-resistor circuit into the Y-type circuit for generating equivalent Y- model network. Similarly, we can change the п-resistor circuit for generating equivalent ∆- model network. So now it is very clear what is a star network circuit and delta network circuit, and how they transform into Y- model network as well as ∆- model network by using T-resistor and п-resistor circuits.
Star to Delta Conversion
In star to delta conversion, the T-resistor circuit can be transformed to Y-type circuit to generate an equivalent Y- model circuit. The star to delta conversion can be defined as the value of the resistor on any one side of the Delta network, and the addition of all the two resistor product combinations in the stat network circuit separate with the star resistor which is placed straightly opposite to the delta resistor being found. The star-delta transformation derivation is discussed below.
