Earth SPD

 
Earth SPD  

In lightning countermeasures, it is very effective to equipotentialize the various earths within a building, but the effect of noise, etc., means that it can sometimes be very difficult to share earths.
An earth balancer tries to address these problems by having the internal arresters normally insulated from the earths, but then having the arresters operate to equalize any electropotential difference that may occur in the event of a lightning strike.
