Abstract:
An extensive testing program for anode breakers using a high-capacity power-rectifier system of the Aluminum Company of America was an unusual opportunity for an appraisal of the combined performance of the system equipment. The information gave an evaluation of the protection to the equipment and has provided a better understanding of the influence of the system components on operating service conditions. This was done with special controls and comprehensive instrumentation which achieved a uniform testing procedure including the rectifier-tank characteristics, phase control of rectifier-tank firing, and interphase transformer saturation control. Through the repetitive consistency of the test arc-back currents, a reliable performance was given by the high-speed current-limiting breaker over the range of available power. In addition, these tests with the large aluminum potline rectifier system gave a real measure of the combined performance of the equipment up to the maximum service requirements rather than by individual device tests, the data for comparison and evaluation of other test facilities, and a guide to future applications.
