### COMPONENTS OF A POWER SYSTEM

1.Alternator
2.Power transformer
3.Transmission lines
4.Substation transformer
5.Distribution transformer
ADVANTAGES OF PER UNIT CALCULATIONS 

• The p.u impedance referred to either side of a 1Φ transformer is same 
• The manufacturers provide the impedance value in p.u 
• The p.u impedance referred to either side of a 3Φ transformer is same regardless of the 3Φ connections YY, -Y 
• p.u value always less than unity.

IMPEDANCE DIAGRAM
• This diagram obtained by replacing each component by their 1Φ equivalent circuit.
Following approximations are made to draw impedance diagram
1. The impedance b/w neutral and ground omitted.
2. Shunt branches of the transformer equivalent circuit neglected.
REACTANCE DIAGRAM 

• It is the equivalent circuit of the power system in which the various components are represented by their respective equivalent circuit. 
• Reactance diagram can be obtained after omitting all resistances & capacitances of the transmission line from impedance diagram
