Zero wire current eliminator

Zero line current eliminator is a unique product to control zero line current, but also for the distribution system three-phase imbalance, the third harmonic is too large new terminal comprehensive control device. It can not only eliminate the fire safety hazard of excessive neutral current, but also solve the complex power quality problem. There are two reasons for excessive neutral current: Unbalanced three-phase harmonic current is too large and 3 times (mall shopping center is the most obvious), LED lights for power supply, switching power supply switch power supply, produce very big, due to 3rd harmonic current of power grids harmonic zero sequence current due to 3rd harmonic current, three-phase vector Angle is consistent, so three superposition of harmonic power flow to the zero line, three-phase unbalance current and flow to the zero line, zero line current is too large.
