R1-3

The use of automatic power factor regulators is required for power factor compensation purposes in installations with variable loads.

CIRCUTOR's “computer” regulators can be used to monitor existing load curves accurately, whereby the cos φ is guaranteed to reach the programmed values.

The whole range of computer regula-tors is based on CIRCUTOR's FCP system (Fast Computerized Program), offering a set of unique performance features:

}} Minimisation of the number of switching operations, increasing the working life of the components in the capacitor bank.

}} Increase in the unit's response time, thus achieving greater energy savings. Anti-oscillation system, preventing unwanted capacitor connections and disconnections. Optimum regulation, thanks to the accurate information about the status of network parameters and the anti-oscillation system, guaran-teeing that the installation load curve can be monitored accurately and the objective cos φ can be attained.

Measurement and compensation

CIRCUTOR's vast range of regulators has been designed to cover the com-pensation requirements in each differ-ent type of installation.


R.1Installation examples:

Power Factor L1: 80 kvarPower Factor L2: 90 kvarPower Factor L3: 110 kvarMean value: L1+L2+L3 / 3 = 93.33 kvar

% unbalance L1= (L1-mean value /mean value) x100= 14.28 %% unbalance L2= (L2-mean value /mean value) x100= 3.33 %% unbalance L3= (L3-mean value /mean value) x100= 17.86 %

The threshold will be used to choose whether our capacitor bank will have a three or single-phase measurement, within a 12% unbalance in one of the phases.

The previous example shows that L1 and L3 are above 12% of the unbal-ance, so the use of computer Plus is required.

In order to compensate installations with quick load variations, CIRCU-TOR's fast series computers must be used, since they are capable of com-pensating the reactive consumption in milliseconds (ms).

In unbalanced systems, if you wish to install a conventional regulator that will measure a single phase, you run the risk of insufficient or excessive com-pensations. CIRCUTOR has designed the computer plus series to compen-sate unbalanced installations. Com-puter plus is available in the plus-T version (contactor switching) and Plus-TF version (thyristor switching), which are capable of compensating the total reactive consumption in real time and phase-by-phase.

Computer Plus is an innovative prod-uct that offers a wide range of new characteristics, three-phase measure-ments, phase-by-phase compensation, built-in power analyzer, test function, protection against harmonics, leakage, control, communications, etc. This cat-alogue includes additional information about our new product.

The following example shows how the unbalance between phases can be calculated in a percentage and how to determine the need to perform a com-pensation process with a three-phase measurement using the Plus system.
