high resistance grounding (HRG) Vs solid grounding 1

[MAS2000]

Can anyone help regarding high resistance grounding (HRG) and solidly grounded system?

I am interested to know what are pros/ cons of both systems. In our utility solid grounding is used for the LV distribution systems.

What advantages can we get if HRG system is used instead?

Another clarification required regarding HRG systems is the voltage rise on healthy phases in event of SLG fault? What is extent of this voltage rise?

Also a lot on HRG here

I-Gard supplies HRG systems, so they have a lot of pros, but not too much cons.

I hope this time works. If so I will send the other files.
