Issue with high resistance pulsing ground

[kroxic]

We have a pulsing ground at I believe 5A on our 600V line to a set of motors. A ground fault occured in one of the motors. The ground alarm triggered and the pulsing ground worked as expected. My question is when the ground is pulsing, will this cause a slight voltage drop for the entire line? Maybe 5% drop?

The 5 amp pulsing ground should not make a noticeable difference on the line to line voltage at 600 v.
It may make a difference to the line to ground voltages but your motors don't see that voltage.
