Hi Guys,

Im currently doing my final year project on high impedance faults and was recently given a new circuit on Digsilent to work on. I was previously using PSCAD and the Digsilent software appears quite different. My main aim is to add in a high impedance fault into the system and would like to know if anyone has any idea how I can do this on digsilent. Previously in PSCAD I was using an arc model involving two DC sources onto one phase however in Digsilent I cannot seem to do this as it says something along the lines of not being able to connect DC sources to an AC line. I have attached an image from PSCAD, the fault type is set to phase a to ground.

The second thing I need to do is monitor the instantaneous value of the 3rd harmonic current and the high frequency current components (such as 2kHz-10kHz, which on PSCAD I previously did with a band pass filter), how can I do this on Digsilent?

Any ideas would be great, Thanks!
