### Do you have an example of an intermittent phase-to-ground fault on a cable?

You will need to perform an EMT-type simulation for this purpose. To replicate the fault on the cable insulation, the cable must be explictly divided in two sections at the point where the faulty…

### How can I implement a load with constant power demand for varying voltage in the simulation?

For RMS simulations the load type has to be set to 100% dynamic load, this means constant impedance Z. Additionally in the RMS dialogue of the load type the voltage dependency of P and Q can be set.…
