A properly sized and connected Grounding Electrode Conductor
I have to disagree with that.
The only electrode that might keep a lost neutral from causing voltage imbalance would be a metal water pipe that is electrically continuous with your neighbors neutral.
If that is the case you have only postponed the problem till someone separates the pipe and gets a shock while doing so.
The other types electrodes, rods, plates, concrete encased etc. will do very little to keep the voltage balanced with a lost neutral.
