SHARE

Medium voltage power factor panels (APFC) are designed to enhance power quality by improving the power factor through the use of capacitors. These panels are essential for compensating reactive power, especially in systems where motors are directly operated without power electronics, which typically have low inductive power factors. The APFC system effectively balances reactive power in real-time, optimizing the power factor and stabilizing system voltage. This leads to reduced transmission losses, improved voltage quality, and operational cost savings. Rated for voltages between 6kV and 35kV, these panels utilize automatic switching capacitors and vacuum contactors to dynamically manage reactive power, ensuring the system operates efficiently. They are especially useful in industries such as steel rolling mills, chemical plants, cement plants, sugar plants, textiles, hospitals, hotels, and public grids, where the load may frequently fluctuate.

Fast return on investment through lower power costs
Power factor correction reduces the reactive power in a system. Power consumption and power costs drop in proportion.
Effective use of installation : An improved power factor means that an electrical installation operates more economical (higher effective power for the same apparent power).
Improved voltage quality
Reduced voltage drops
Optimum cable design : Cable cross-sections can be reduced with improvement of power factor (less current). In existing installations for instance, extra or higher power can be transmitted.
Reduced transmission losses : The transmission and switching devices carry less current, i.e. only the effective power, meaning that the ohmic losses in the leads are reduced.
