Thanks to everyone for all the thoughts and responses on this problem.
I just wanted to provide some clarification to my initial statements and answer some of the questions that were asked. The current at the ground bond at the neutral of the transformer has been measured at as high as 50 A...
I have encountered a situation in which a measurable ground
exists in a low voltage power system. The system is a 277/480 Vac three phase power system derived through a 2000 kva transformer fed from a 13.2kv service. The transformer neutral is solidly grounded. The main breaker has ground...
