  • Reactive power compensation panels are used to reduce a contractors load in the Electrical grid and to save costs. This is the reason, that there are Special requirements for the control units of these compensation panels, the reactive power regulator.
  • The most important task for the reactive power regulator is to control the reliable termination of reactive power. This is reducing the costs for electrical energy. Cables, transformers, switch components and power distribution are unloaded by reducing reactive power.
  • Another task of the reactive power regulator is monitoring the compensation panel and giving alarms.
  • All of these requirements are solved by Beluk reactive power regulators with their patented regulation principle. By continuous measuring of the capacitor power, the steps are always used with their exact capacitor ratings. The regulation program is only defined by the choice of the capacitor sizes. There are no limitations and no settings for step sequence are necessary at BLR-CX. If BLR-CX cannot recognize anymore the function of a step e.g. caused by damaged capacitors, contractors or blown fuses, then it shows alarm. The integrated alarm relay with sign-of-life contact can forward this also to a control room.
  • BLR-CX is calculating by the measuring of current and voltage the power conditions in the electrical network. Generally, it's not important, in which phases voltage and current are connected because the connection is corrected by BLR-CX after starting the automatical phase correction. The min. sensing current is 15mAmp, which ensures a reliable and exact regulation. For the current measuring 1Amp, CTs can be used as well as 5Amp CTs for this, there is no manual changing of any settings necessary. The wide range SMPS allows realizing voltage measuring in a range between 90 V and 550 V.
  • By using the temperature sensor, BLR-CX can measure the internal temperature of the compensation panel and can switch by using one of the exits relays a fan. The switch-off of the capacitor steps due to over temperature can be triggered by N/0 contacts of external thermostats, which are connected in parallel to the temperature sensor.

  • The monitoring features of BLR-CX guarantee a reliable operation and a long life of the compensation panel:
  • Low voltage switch-off against chattering of contractors
  • Overvoltage switch-off for protecting the capacitors
  • Over temperature switch-off
  • Monitoring of THDU
  • Recognition of defective capacitors
  • Alarming, when target o regulation cannot breached
  • Signaling of the need for maintenance Fan control
  • Failures and announcements of the panel are shown in LCD
  • Failures can also be forwarded by the volt free alarm-contact (sign-of-life signal)
  • For switching the fan, one of the step-exits has to be used.

Advanced Products:
  • For real time compensation
  • For individual compensation in all 3 phases
  • Thyristor switches

Principle of Regulation:

  • Stepped regulation with the following modes: Best-Fit: starting with the biggest exits; LIFO: last in-first out; Comb filter: Best-Fit, with a more connected power of odd exits; Progressive: all required exits are switched in quasi one operation Automatic detection and correction of the phase of the phase of current voltage connection;

Special Feature:

  • Automatic detection of the used exits; Over-and under voltage monitoring; Monitoring of THD U; Over temperature switch-off

Information Display:

  • Switch cycles per step, capacitor rating, a status of the exits, Operating hours of the panel, max. temperature, average PF
