    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1375 KB)

    Equations are developed for the transient temperature cooling of the transformer cooling medium and for various types of transformer coils over their ambient medium. These have been evaluated on a percent temperature rise base for various powers of the watts dissipated and for both constant watt and constant current input. Some special cases of cooling are derived from the general transient temper... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (763 KB)

    Capacitive regenerative braking may occur in capacitor start motors when power is removed. A series resonant circuit is formed with the main winding and start winding connected in series through a relay or centrifugal switch to the start capacitor. The circuit will resonate over a range of speeds. Slip (which is negative) and saturation are determined by the conditions that the sum of the real imp... View full abstract»

  • Late Model 230-kV Oil Circuit Breaker

    Publication Year: 1967, Page(s):1317 - 1328
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (6537 KB)

    Recent reports on the performance of oil breakers give the impression that they are not suitable for use on modem transmission systems. They imply that oil circuit breakers have reached a design maturity and that they cannot be made adequate for today's use. The record should truthfully say that these comments are applicable only to older oil circuit breakers and not to those of modem design. A 23... View full abstract»

    This study was made to identify, photograph, and establish the radio noise importance of the fair-weather coronas occurring on an ac high-voltage transmission line conductor. Excursions of fair-weather interference to over ten times the base value of the line noise are attributed to corona plumes from vegetable particles and insects attached to the conductor. Vegetable particles and insects are di... View full abstract»

    The ac power flow problem can be solved efficiently by Newton's method. Only five iterations, each equivalent to about seven of the widely used Gauss-Seidel method, are required for an exact solution. Problem dependent memory and time requirements vary approximately in direct proportion to problem size. Problems of 500 to 1000 nodes can be solved on computers with 32K core memory. The method, intr... View full abstract»
