how to do pole to ground fault analysis on dc transmission line

we can figure out pole to pole faults on dc transmission line by using 3phase fault block as it works for 1 phase but we are unable to figure out how can we analyse this in a dc transmission line either on the postive line or negative line

Hi,

You can provide pole to ground fault on dc transmission line with the help of circuit breaker connecting between pole and ground. Once it happens you can observe all the parameters using a measurement block.
