If there's a significant drop in the current demand of a power grid, the voltage of that grid could possibly jump.
If enough of the loads are dropped, I guess there might be some power factor issues and power reflections back to the companies. Not sure, but I think a large reflection bouncing around the Northeast grid is what popped most of the substations during the famous power outage in New England during the 60's. - Doug McKean ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
