摘要：system and method for identification and production of reactive power compensation for the inductive load. a reactive power compensator (50, 50 ') monitors the voltage and current through each of the three lines (52a, 52b, 52c, distribution, which provides three-phase power to one or more inductive loads.using signals from the power in each of these lines when the voltage waveform of the line through the origin, the reactive power compensator determines a capacity of reactive power compensation, to be connected to the line in may ntenir a var, a power factor and a desired line pressure.according to another embodiment, a user may manually select a specific ability of connecting to each line, and the capacity can be selected on the basis of a program.the reactive power compensator generates control signals, which are coupled by optical fibers (102 \/ 106), a driving switch (110, 110 ') in order to select specific compensation capacitor (112) for connection to the line.the driving circuit of the switch trigger produces signals transmitted to a plurality of semiconductor switches (350) are connected in series, in which the load current in a direction relative to the earth for each compensation capacitor.
