Test and operating experience with the triple-diametric rectifier

THERE is an ever-present demand for improvements in electric equipment. To improve the equipment, the engineer may try many new ideas. Some of these will yield results while others will be discarded as not being worth while. On equipment such as mercury-arc rectifiers many ideas have been successful and the improvements have been frequent and substantial. Usually, the engineer has so many new ideas to try that he does not take time to re-examine old ideas in the light of recent developments.
