How to Simulate High-Voltage Network Faults in a Cascaded Transmission System Using ETAP Analytical Tools

A high voltage circuit in scale 220 kV cascade transmission lines was simulated with the ETAP Real-Time. This circuit was validated with experimental data obtained from a scaled circuit in laboratory, where load flow and short circuit analysis were tested.
