The releasing of this heavy load produced a voltagekick which was anywhere from one and a quarter timesto twice normal voltage. If the compressors were run-ning at the time they invariably flashed over, blowingthe fuses. In order to overcome this difficulty various plans weretried, such as the use of choke and resistance coils inseries with the compressor motor circuit, but these af-forded very little satisfaction. It was finally decided tobuild a relay that would operate at 725 volts and, onapplication of this pot
