Your grounding rod to your neutral connection (within the service drop transformer) will strongly hint whether or not you have a potential ground loop problem looming on the horizon. Measure the differential then retest for a few days running under different AC hotel loads.
Line to Neutral versus Line to Earth Ground voltage differential is another algebraic test.
Why is this important?
When it rains a problem can cause a lot of excitement within your electrical system.
Nearby large ground based industrial transformers can be hair raising experiences with poor soil conductivity. I have measured 247 volts line to line, and 320 volts line to earth ground.
