Reactive Power Conditioner

The PFC LITE uses high speed IGBT inverter technology to control reactive power flow inside the facility.

The PFCs automatically detect any power fluctuations and respond within less than a cycle to provide the needed reactive power. They also continuously monitor and correct power factor despite large power variations.

Reactive Power

Reactive power (VArs) is either generated or absorbed by inductive loads or capacitors in the network to maintain a constant voltage level. The PFC LITE maintains a constant voltage level, a stable power factor, and a controlled reactive power flow.

Control Mode Options

The control mode defines the main operation of the PFC LITE, either control power factor to a preset value (programmable) or control voltage to a preset value.

Additional functions can then be enable in addition to the main control mode including:

  • Flicker Reduction
  • Low Order Harmonic Cancellation
  • Unbalance (negative sequence) correction
  • Voltage Clamping

Frequent Ask Questions

Explain reactive power

On an AC power system, there are two kinds of power - real power (kW) that does the work, and reactive power (kVAr) that enables the operation of transformers, generators and motors. Capacitors can be used to counteract the reactive power from inductive motors.

What causes reactive power in a system?

Positive reactive power is caused by inductive loads e.g. motors or transformers. Negative reactive power is caused by capacitive loads e.g. variable frequency drives, switch-mode power supplies and inverters.

When is reactive power compensation necessary?

Starting largemotors.

In general, more reactive power is needed for a load with a power factor of less than 0.95. For a load, a power factor number greater than 0.95 indicates that the power is being used more efficiently, and a value of 1.0 indicates that the load is perfect and uses no reactive power.
