Reactive Compensation
NC SPC detects load current through an external current transducer (CT) and analyzes the reactive component of load current by the DSP controller. Then it controls the IGBT inverter to generate reactive current and compensate load reactive current to meet the target of line power factor.
Three-phase Balancing
NC SPC detects the load current through an external current transducer (CT), analyzes whether the system is balanced or not, and also calculates the required SPC current, and sends the signal to the IGBT. Then the unbalanced current is transferred from the high-current phase to the low-current phase. Finally, the three-phase current is balanced at the source site.
Voltage Support
The NC SPC samples the voltage at the compensation point and sends the voltage signal to the DSP controller for comparison with the set value. When the voltage exceeds the Umax value, the NC SPC generates an inductive current to reduce the voltage. When the voltage is below the Umin value, the NC SPC outputs capacitive current to increase the voltage. Finally, the NC SPC stabilizes the voltage in the normal range.

M/s Zaman Textile Mills in Pakistan400V 100A APF wall mount + 400V 150A APF3 sections in total. The harmonic distortion rate before compensation is 38%, 24% and 32% respectively, and after compensation, they are all around 5%.The operation is stable and the customer is very satisfied.
Nancal Electric's Active Power Filter (APF) has been successfully deployed at a large packaging factory and a textile plant in Pakistan. Following the implementation of the APF, harmonic levels at the facilities were significantly reduced, meeting relevant power quality standards. The power supply environment has improved markedly, leading to a substantial increase in the stability and continuity of production lines. Nancal remains committed to providing overseas customers with efficient and reliable power quality solutions, supporting their industrial upgrade efforts.
