These two huge generators, largest ever built for short-circuit testing, combine to produce 200,000 amperes of short-circuit current utility systems. They are located in the test building of the General Electric Company's new Switchgear Development Laboratory in Philadelphia, PA. To absorb the tremendous shocks produced during short-circuit tests, the stator of each generator is supported on huge spring-steel legs. These "legs" allow the stator to rotate through a small angle and still remain in perfect alignment with the rotor shaft. The springs, instead of the generator winding and foundations, take the brunt of the shock. When operated in parallel, the generators, each nominally rated at 125,000 kva, can deliver 5,250,000 kva asymmetrical, 3,200,000 kva symmetrical at 15.5 kv
