A smart solution

Why compensate the reactive power of your plants?

Since January 1st, 2016 the AEEGSI (Electric Energy and Hydraulic Systems Regulator) has forced reactive power penalties to LV and MV users, having more than 16,5 kW power installed.



Economical benefits

  • Avoiding/Reducing maintenance costs > POWERWORX does not need expensive maintenance actions
  • Saving on company investments > POWERWORX can be used together with the existing reactive power compensation systems, so avoiding total replacement of old system to fulfill new regulation limits
  • Avoiding reactive power penalties in all conditions

Technical benefits

  • Energy saving along the electric plants
  • Optimization of the wirings providing energy to compensated loads
  • Optimization of existing reactive power compensation systems
  • Suitable for all types of loads (even in presence of harmonics or heavy fast changing loads)

What is the reactive power compensation?

Electric loads convert electric power into other types of power

Electric cookers convert electric power into heat power
Engines convert electric power into mechanical power

The electric power is of two types

Electric Active Power (P-kWh, included into electric consumption invoices): it is converted into useful energy types (heat, mechanical, etc…)

Electric Reactive power (Q-kWarh, included into electric consumption invoices only for not household users with more than 16,5 kW power installed, Low Voltage-LV or Medium Voltage – MV): it is used by some loads because of their intrinsic operating principle (based on magnetic fields) but it is not converted in any useful power.

The Electric Regulator (AEEGSI) want to limit reactive power flows along the grid, as they cause energy losses.

REACTIVE POWER COMPENSATION means providing on-site the reactive power needed by loads, in order to avoiding reactive power flows along the grid.

Electric cookers: convert all active power into heat power
Engines: require reactive power to convert active power into mechanical power

Who has to deal with the reactive power compensation?


Small and medium size users, with more than 16,5 kW power installed. In particular, POWERWORX is perfect for fast variable loads and in presence of harmonic distortion. These types of loads are not easily managed by traditional reactive power compensators (switched capacitors based).

How does the POWERWORX work ?

Powerworx measures the reactive power absorbed by the load and instantaneously delivers the exact amount of reactive power required, within its maximum range (10 kVar). This mode of operation maximizes the energy savings. Powerworx has been designed for distributed applications, so, it has to be installed as near as possible to reactive loads.



  • Provides the exact amount of reactive energy required by the loads
  • Provides both inductive and capacitive reactive power
  • Immune to harmonic distortion
  • Provides measurements at the installation point
  • Allows the possibility of creating a distributed reactive power compensation system, remote controlled

Traditional reactive power compensators

  • Provide the nearest discrete value of reactive power required by the load
  • Provide only capacitive reactive power so they cannot avoid over-compensation situations
  • Suffer in presence of harmonic distortion
  • Do not allow remote monitoring of electric characteristics of its installation point
  • Are not suitable for distributed reactive power compensation
