Low Voltage Compensation System

Low Voltage Compensation System

In ferroalloy production, the efficiency and stability of submerged arc furnaces are strongly influenced by the operating power factor. After commissioning, the natural power factor of a newly built furnace is typically only 0.60–0.65. Such a low power factor leads to higher reactive power consumption, increased transformer and network losses, and limited effective utilization of furnace transformer capacity.

CHNZBTECH provides advanced Low Voltage Compensation (L.V. Compensation) Systems specially designed for submerged arc furnaces. The system improves the operating power factor to 0.90–0.95, allowing more transformer capacity to be utilized as active power for smelting. This contributes to improved furnace productivity, reduced power consumption, and more stable furnace operation.

Key Features of Low Voltage Compensation System

• Power Factor Improvement: Increases furnace power factor from 0.60–0.65 to 0.90–0.95.

• Higher Effective Power Utilization: Enables the furnace transformer to deliver higher effective active power for smelting.

• Energy Efficiency: Reduces reactive power losses and lowers electricity consumption per ton of ferroalloy.

• Stable Furnace Operation: Improves arc stability, reduces voltage fluctuation, and minimizes electrode current imbalance.

• Reduced System Losses: Decreases transformer and grid losses, improving overall power utilization efficiency.

• Customized Design: Tailored solutions according to furnace capacity, transformer rating, and smelting process requirements.
