    A new high-resistance ``thyrite'' and a new 3-element cold-cathode tube having unusual characteristics constitute the basic elements in a new high voltage relay combination for relaying or detecting ground faults on ungrounded systems. This scheme of protection, as described herein, is characterized by its reliability, simplicity, sensitivity, and low cost. It has been found to be particularly val... View full abstract»

    Losses in induction machines have been subjected to a detailed study by many investigators, but due to the complex nature of some of these losses, particularly several forms of load loss in induction motors, a clear understanding of their nature, has not been available. Since the majority of such losses are connected with the magnetic flux in the machine, a study of the distribution of magnetic fl... View full abstract»

    The amplification obtainable in a vacuum tube amplifier is limited by the noise in the circuit. Of the various sources of noise the most fundamental and inevitable is thermal agitation of electricity. Other sources are the influence of ions and of shot effect and flicker effect on the current in vacuum tubes, poor contacts, mechanical vibration, and hum from a-c cathode heating. These noises and t... View full abstract»

    Because of the scarcity of published records of lightning performance of 220-kv power transmission lines, the A.I.E.E. lightning and insulator subcommittee* has attempted to collect such data by means of a questionnaire sent to the various companies operating 220-kv lines in the United States and Canada. The data thus obtained is summarized in this paper. View full abstract»
