- •
The general fault admittance method was used to solve a metallic fault.
- •
Simulating the four-impedance three phase balanced metallic fault was a challenge.
- •
Short circuits replaced with low impedances gave the best simulation convergence.
- •
Results validate solutions from classical approach for a positive sequence network.
- •
The method eliminates need for sequence component networks layout.
