Can somebody please explain what is meant by an ungrounded system, while not having any intentionally applied grounding, is grounded by the natural capacitance of the system to ground? What is meant by the natural capacitance of the system to ground? Is there actually capacitance between an overhead conductor and the earth??? How does capacitance provide a ground in the system? How does this keep fault current low? Thank you for all of your previous replies, and I look forward to a discussion on this as well.
