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.
