Tests of grounded phase protector on the 44,000-volt system of the Southern power company

The Southern Power Company experiences every year during the lightning season frequent disturbances and interruptions due to the lightning starting an arc over the insulator to the pin, this arc often breaking the insulators, or sometimes even burning off the line. With the object of extinguishing this arc before it has time to do any damage, an automatic insulator protector has been installed on the 44,000-volt system at the Catawba power house.
