What is the strongest indicator of spatial depth?

Protectors earth indicator?

• I own a Belkin SurgeMaster Gold and it has a indicator telling if its grounded correctly. Resently the earth indicator didn't glow so I tested my ground by connecting the live wire to the ground wire and our safety swich did go off. And suddenly I noiced that at night the earth indicator works and in the morning it stops working (indicator). So I powered the surge protector via my generator and the indicator worked without an problem as well! I also took the protector to a few houses and the earth indicator worked just fine. I contacted my local power station and they said it might be a leak in the natural wiring. But the problem is why does the the earth indicator work during the night? if its a leak it shouldn't glow all the time right? This is very confusing. I also tried the following: Unplugged everything in the house and just ran my protector Turned off all breakers except my rooms and turned it on Plugged it in all the sockets in the house and it still didn't work :(
