Reclosers in general, and specifically reclosers with single-phase tripping capability, have the ability to improve distribution system reliability significantly not just on the distribution feeder but also in wind generation, cogeneration, various motor loads, oil wells, agricultural entities, small industrial sites, and at substations that feed moderate rural, residential, and commercial loads. The intelligence built into today's microprocessor- controlled reclosers allows the devices to dynamically operate on a single-phase or three-phase basis depending on the applications and conditions (see Figure 11). Loop systems can further enhance the reliability of a power system through sectionalizing or removal of faulted line sections.
