Transformers, electric motors, ballast coils, air conditioning systems etc, comsume reactive energy. Reactive energy circulation leads to:

  • increased costs in electricity bill
  • increased equipment costs by increasing the installed power
  • additional losses of active and additional voltage drops in conductors
  • decrease available power in the secondary of the transformer

Reducing the above mentioned equipments is made via automatic compensation of reactive power, made with the following basic components:

  • compensation capacitors
  • contactors for connection / disconnection of capacitors
  • power factor controller

The compensation is achieved by calculating the reactive power consumed permanently, based on direct measurement of phase voltage / line voltage and phase using an external current transformer. Depending on the calculated value of power factor regulator control circuit inserting or removing the gear compensation after a predetermined adjustment program.

Main technical characteristics of switchboards for reactive power compensation:

  • Rated power: – 22.5 … 100 kVAr in enclosure                                                                                                     – 300 -100 enclosure kVAr in kVAr in cabinet
  • Nominal voltage: – 230 … 240 V / 50 … 60 Hz                                                                                                          – 400 … 415 V / 50 … 60 Hz
  • Number of speed control: – 1 … 6 with R6 Varlogic regulator                                                                                                – 1 … 12 with R12 Varlogic regulator
  • Panel size: – 500x500x250 mm minimum                                                                                                          – maximum 600x800x2000 mm
  • Working temperature: 0 … + 45 grd.C
  • Protection level: IP30 – IP55

EETim SA implemented equipment for reactive power compensation:

  • VarPlusCan pole capacitor modules / VarPlusBox – Schneider Electric, or Enerlux
  • Power factor controllers: Varlogic R6 / R12 Varlogic (Schneider Electric)
  • Contactors: LC1-DK Series (Schneider Electric)

The ARA can be of three types:

  • AAR system with two power supplies: Transformer / Generator
  • AAR system with two power supplies: Transformer / Transformer (with coupling)
  • AAR system with three sources: Transformer / Generator / Transformer

The AAR system component includes the following products in the Schneider Electric:

  • Zelio programmable relay (for currents up to 100A) or UA programmable relay (for currents over 100A)
  • Range of switches: – Compact NSX (100 A – 630 A)                                                                                                       – Masterpact NT / NW (630 A – 6300 A)
  • Separator Interpact (40 A – 630 A)

Features:

  • allows switching from the main sourse to the secondary source within a programmable time
  • does not allow simultaneous closing of the devices
  • status indication by tripping caused by short circuit breakers
  • Reset is made manually or automatic

Applicability:

  • in institutions where continuity of power supply is vital
  • in continuous flow systems
  • in areas where electricity supply has problems
