Do you have an example of modelling a single phase line-to-ground fault for overhead lines?

Answer

In the provided PowerFactory project, a single phase line-to-ground fault in the middle of an overhead line can be analysed using EMT simulation. The simple network model contains a 110 kV overhead line in which the study is performed.

The single phase line-to-ground fault is caused by a conductor failure in the middle of the line. Therefore, in the simulation, phase C is first separated halfway along the line by opening a breaker (which is included for the sole purpose of making the line separation). The breakers on both sides of the separated conductors of phase C are used to simulate the short circuit between phase and ground.
