The capabilities of Project UHV to apply switching surges to a test line are described. Switching surges with times to crest between 1000μs and 4000μs, similar in shape and magnitude to those which could occur on 1200 kV transmission lines have been generated. The initial results obtained on rod-plane gaps, conductor-to-tower, and conductor-to-grounded objects are described.
