Unsymmetrical Fault Calculations | part of Understanding

The calculations of unsymmetrical faults are important applications of symmetrical components. Unsymmetrical faults are more common. Approximately 70% of the faults in power systems are single line‐to ground faults. While applying symmetrical component method to fault analysis, the load currents are ignored. Transformer windings can be connected in wye, delta, zigzag, or

Introduction to Symmetrical Fault in Power System:

The synchronous generator during short circuit has a characteristic time-varying behavior. In the event of a short circuit, the flux per pole undergoes dynamic change with associated transients in damper and field windings. The reactance of the circuit model of the machine changes in the first few cycles from a low subtransient reactance to a higher transient value, finally settling at a still
