Test Preparation

Basic introduction of fault, it's reasons, different types of faults are discussed briefly

Introduction to Fault

Current nature in case of short circuit in transmission line is discussed

Transient in transmission line

Sub-Transient, transient, and steady state synchronous reactance has been discussed here in detail

Short circuit on synchronous generator at no load

Per unit system is described with examples

Per unit representation

Representation of different electrical components by reactance is described and based on that impedance diagram of a circuit is derived.

Impedance diagram

Calculation of short circuit current is done using an example

Fault current calculation

Fault level, fault MVA is described and based on that circuit breaker operation is briefed and key points are also covered

Selection of ckt breaker

Finding the voltage behind synchronous reactance and deducing the fault current is discussed with an example

Short circuit on loaded condition

Using Z bus matrix of a network fault current and bus voltages are computed in step by step process

Fault current from Z bus matrix

Two methods of formation of Z bus matrix is described here. First, from Y bus matrix and second, by current injection method

Formation of Z bus
