  • Discussion on ¿The use of electricity in the production of calcium carbide¿ before the Utilization Section, 18th November, 1954
    transference of these switching surges to the 220 - volt busbars in a greater proportion than one would normally find in a trans- former of more normal reactance.
  • Discussion on ¿The use of electricity in the production of calcium carbide¿ before the South Midland Supply and Utilization Group, 8th November, 1954
    transference of these switching surges to the 220 - volt busbars in a greater proportion than one would normally find in a trans- former of more normal reactance.
  • A Brief Technical Description of the New San Diego, Pearl Harbor, and Cavite High Power Naval Radio Stations (Supplementing Captain Bullard's Paper)
    This feature holds for San Diego and Cavite as well as Pearl Harbor and in all three the usual antenna grounding switches, transfer switches , etc., will be provided. The generating equipment at Cavite will be identical with that at Pearl Harbor except that the power supply will be 220 - volt direct current and no over-hung exciter will be used.
  • Optimal deployment of power reserves across telecom critical infrastructures
    Virtually all critical information tech- nology facilities include permanently installed engine- generator backup systems on site, plus their associated automatic transfer switches (ATS) to protect against sustained commercial AC power system failures. Information technology equipment is tradition- ally powered by AC power, typically 120, 208, or 240 volts single phase AC in 60 hertz countries or 220 –240 volts single phase AC in 50 hertz countries.

  • AC/AC power conversion based on matrix converter topology with unidirectional switches
    For the open-circuit problem, the switching of the rectifier bridge is forced to occur only in the zero vector period of the in- verter bridge, when the load current is not transferred to the rec- tifier bridge. … voltage drop of an IGBT and its diode give a margin of several volts for the switching … The margin is equivalent to several microseconds in the case of the 220 -V/60-Hz source.
