FAQs

When should the NWC1 Self-healing Shunt Capacitor be used?

The NWC1 is ideal for low-voltage power systems (≤1000V) that require reactive power compensation to improve power factor and energy efficiency. It’s widely used in industrial distribution panels, commercial facilities, and substations where voltage stabilization and harmonic control are critical.

What makes the NWC1 capacitor “self-healing”?

It uses metallized polypropylene film that isolates damaged dielectric areas automatically after breakdown, maintaining continuous performance and extending service life without the need for manual repair.

Can it be used in environments with harmonic distortion?

Yes, provided THDU ≤5% and THDI ≤20%. For higher harmonic conditions, CHINT recommends series reactors or detuned filters to prevent overheating or resonance.

What precautions should be taken during installation?

Avoid installing near heat sources or vibration. Use specific contactors and protection relays, ensure proper ventilation, and do not connect the capacitor directly to current-regulated systems or unloaded transformers to prevent over-compensation.

How does the NWC1 ensure operator safety?

It integrates self-discharge circuits that reduce residual voltage below 75V within 3 minutes, and the double-shell metal housing provides enhanced electrical insulation and fire resistance for safer operation.
