    Patent number: 4529926
    Abstract: Power factor regulating method and an apparatus embodying the method in which each of three condensers, which are to be connected to each phase of a three phase distribution line, is preliminarily charged with approximately peak line voltage while a load connected to a distribution line is opened in order to lessen impulse waves that are brought about at the time of connection of the condenser to the appropriate phase of the power line. The present method needs no conventional discharging coil.
