Metal-Enclosed Reactive Compensation

CVAr (Standard and Point-on-Wave Switched)

Enspec Power specializes in the design and manufacture of reactive compensators. Reactive compensation provides any shortfall in reactive capability that is a crucial part of power quality compliance, and therefore a key requisite for exporting electricity and generating income.

What is Reactive
Compensation?

Reactive compensation is the process of adding or injecting positive and/or negative VAr’s to a power system to attain voltage control. Depending upon the application, it can be achieved passively with capacitors and reactors, or actively with power electronic solutions, such as STATCOMS and Static VAr Generators (SVG’s).

More significantly, reactive power is an essential component of an electric power system. Rotating machines could not rotate without it, transmission lines could not transmit active power - and the ability to control or compensate reactive power offers huge benefits.

Reactive compensators to suit your needs

MVAr equipment ratings are typically specified following the necessary power system studies that can be carried out by Enspec or third-party engineers. Once a finalized specification is agreed, we will offer the most cost-effective, technically acceptable solution to your needs, be it passive, active, or hybrid reactive compensation.

The Enspec solution

We design and manufacture reactive compensators, fully enclosed at distribution voltages from 400V to 36kV and open-rack at higher voltages. We offer a range of technologies including:

  • Passive – Power capacitors and shunt reactors provide the required VAr output. These can be simple non-switched biasing solutions through to Point-on-Wave switched systems to avoid transients during switching.
  • Active – Utilizing power electronic solutions such as STATCOMS and Static VAr Generators (SVG’s), these inject real-time VAr’s for dynamic changes in load and enhanced fault ride-through capabilities.
  • Hybrid – A combination of both passive and active technologies provides a cost-effective solution, most often used within renewable energy applications such as wind farms.

Add up the benefits for yourself

  • Free up the power capacity of the facility
