Dry Bulb, Wet Bulb and Dew Point Temperatures Dew Point temperature is always lower than the Dry Bulb temperature and will be identical with 100% relative humidity (the air is at the saturation line). As air temperature changes the Dew Point tends to remain constant unless water is added or removed from the air. The Dew Point temperature can be measured by filling a metal can with ...

Buying, selling or living near a substation a large National Grid substation, you would need to be within metres or maybe tens of metres of the perimeter to get an elevated field. It would be rare to live that close in a rural setting but could happen in an urban setting. But you would probably be getting a higher field from the lines or cables entering the substation.
