- Power Quality Improvement
  - back
  Power factor is an important parameter to measure the efficiency of electrical equipment. The high power factor indicates that the reactive power of the circuit for alternating magnetic field conversion is small, the utilization rate of the device is high. Low power factor indicates the reactive power of the circuit for alternating magnetic field conversion is large, which reduces the utilization rate of the device and increases line power loss.
  Compere provides capacitor, reactance, active filter, power factor controller, etc. to increase power factor and reduce the line power loss.
