Date:12/18/2015 03:30:12 PM

The harmonic control project is located in Chengdu High-tech Zone, an international hotel low-voltage power distribution system. The harmonic control is for the 2 # transformer. The load type is mainly single-phase LED energy-saving lamps, in the electricity process to produce a large number of leakage current, third harmonic and unbalanced current. Harmonic current total distortion rate THD is too large, resulting in the transformer terminal of the main circuit breaker grounding protection current is too large, increasing the probability of circuit breaker tripping, seriously affecting the hotel's normal operation and safety of electricity.

In this regard, by the Chengdu Malone Electric Co., Ltd. in the 2 # transformer low-voltage side to provide a set of power active filter (M-APF380-300-4L / D). In December 28, 2015 02:00 official commissioning operation, after 72 hours of trouble-free operation after the harmonic control effect is obvious.
