Aaron, If you read back in this thread (using the NANOG mailing list archive), you’ll find this has been explained in great detail. In a nutshell, phase grounding won’t help if a generator is energized from the customer end, and this technique was discontinued in the 1970s due to the many deaths that resulted.

Would you care to educate me on this? If you ground the phases on both sides of the work-site, how are you going to end up being a better path to ground? -A
