User: Lecong Yinfu Furniture City Name: Zero sequence filter Model: ZSFGD-150/0.4 Load: LED energy-saving lamps, billboards, large-size LED screens Before filtering: 1. Transformer noise is large: up to 65dB 2. High cable temperature, fire hazard: 83 ° C 3. Zero line current is large: 368A (phase line 260A, basic balance) 4. Neutral current: More than 90% is the 3rd harmonic. After filtering: 1. Abnormal noise disappears: from 62dB to 45dB; 2. The temperature of the neutral cable is reduced: from 83 ° C to 47 ° C; 3. Zero line current reduction: from 368A to 129A; 4. ABC current reduction: Phase A drops from 261A to 228A 5. The energy saving effect is obvious: reduce the loss by 6kW.
