What is “reactive energy”?


Induction or capacitive reactive energy is the energy generated by all working devices, transferred to your electrical network. The user is charged additional fee, indicated on an invoice, for the reactive energy increasing the active energy consumed by devices.

What generates additional costs?

The value of reactive energy (which you don’t use, but pay for) tolerated by all energy network operators is included in the power factor parameter, expressed as tgφ. The parameter should stay within the range of 0–0.4. 0.4 tgφ is the critical value; upon exceeding it, you will be charged high additional fees.

Why does reactive energy cost so much?

Non-compensated reactive energy generates additional costs, exceeding up to 30% of energy distribution bills, and most importantly generates the risk of higher machine wear.

Typical work conditions of the device Parameter
Current amperage from 3.1 kA
Independent overload protection system yes
Independent measurement data recording and archiving microSD card
Archiving period, dictated by the microSD card capacity e.g. for 2 GB card – archiving period of 1 year
Rated compensator work voltages 110V, 230V, 400V
Work frequency range 48-60 Hz
Rated power 30 - 600 kVar
Measurement current of the microcontroller max 5A
Work temperature range from -200°C to +400°C
The device has CE compliance declaration

Opinion of a research institute – Mechatronic Engineering Department of the Faculty of Electricity of Silesian Technical University
The Polish manufacturer provides 2-year warranty for the Twens-eR compensator. Having rich experience in the exploitation of Twens-eR compensators, we can offer the extension of warranty by another 2 years.

The life expectancy of the device is approx. 10 years.

The process without secrets:

  1. Electrical energy payment analysis on the basis of invoices
  2. Report with energy effectiveness analysis
  3. Reduced fees for reactive energy on an invoice demonstrates the effectiveness of Twens-eR
  4. Electrical measurements on-site
  5. Adjustment of power and number of steps of the reactive energy compensating device
