Abstract:
    The utility model relates to an automatic reactive compensated controller. It is composed of a voltage sampler, a zero passage comparator, a phase difference distinguishing measuring instrument, a microprocessor, an on-off controller, an event indicator of reactive current power factor, a reactive current measuring instrument and an order assemble electronic switch. All the elements except voltage, electric current sampler and reactive current power factor event indicator are installed on a piece of circuit board, welded with connection terminal, inserted into a control shell and locked by bayonet lock. No actions over voltage and surge electrophoresis phenomenon happen. It has advantages of increasing compensation efficiency, increasing electric network quality and output ability of equipments, reducing line loss, saving energy, small size, light weight, low cost, strong anti-jamming ability, fast arithmetic speed and high sensitivity.
