The economy quickly back to the power supply easily carried out, is the widespread use of the linear device so that a large number of harmonic current is injected into the power grid, not only adds power consumption benefits, a decrease of harm economic efficiency, and severe impact of power quality, threatening power crisis Qi run. Is of special agriculture, steel rolling and smelting industry, the formation of a large number of zero-current income shop, and electromagnetic frequency changes along a linear bearing cross back into the power grid operation, place a small amount of harmonic current war voltage, the system lost over current, over voltage, over the back Netherlands. The case of such electricity, provide the following information for the user:
      1, there is no wide-Shen harmonic users should choose Power down high-voltage capacitors, 450V or 525V with power capacitor voltage level.
      2, the harmonic current stability is not critical, but small, the choice should be progressive voltage power capacitor, capacitor outside the reactor by demolition, the best cover for warmth by demolition.
      3, harmonic wider user Shen, each power capacitor voltage should be progress, but the quality we have to change a large capacity. AC contactors, reducing the capacity of melting continued control, harmonic vibration can be the fruit of Enlightenment attack large currents.
      4, harmonic serious users, each installed power capacitor filter put in when the less, that filter installed to measure not based on the user double-data set for the harmonic.
      5, double-harmonic power, the choice of active control devices to make up initiative, will require anti-harmonics. Divide Frankly, the power cut when the capacitor matching, can ensure power quality, diligence and motivation, without the need to maintain electrical equipment. Source: Network
