Electrical Shock from Ground Cable
Electrical Shock from Ground Cable
(OP)
Are there any documented cases of a person being shocked or electrocuted as a result of disconnecting the shield ground of a high voltage cable.
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Electrical Shock from Ground Cable
I don't know of any instances that fit your specific scenario, but the possibility of death or injury is quite high if a shield ground connection is cut.
Within the last year or so, someone posted a picture on this site. It was the burned body of a thief who had just cut the grounding cable of a large transformer.
I have seen documentation on several accidents caused by ground currents and voltages on inadvertently cut ground connections.
On a small system, the hazard of an open ground connection may be negligible. On a large system there will be potentially lethal potentials if a shield ground is opened. Single conductor cables are much worse than three conductor cables.
Under fault conditions, or if a cables is starting to break down, the hazard is much worse.
