Automatic power factor regulatorsAutomatic power factor regulatorsThe use of automatic power factorregulators is required for power factorcompensation purposes in installationswith variable loads.CIRCUTOR's “computer” regulatorscan be used to monitor existing loadcurves accurately, whereby the cos φis guaranteed to reach the programmedvalues.The whole range of computer regulatorsis based on CIRCUTOR's FCPsystem (Fast Computerized Program),offering a set of unique performancefeatures:}}Minimisation of the number ofswitching operations, increasing theworking life of the components in thecapacitor bank.}}Increase in the unit's response time,thus achieving greater energy savings.Anti-oscillation system, preventingunwanted capacitor connections anddisconnections. Optimum regulation,thanks to the accurate informationabout the status of network parametersand the anti-oscillation system, guaranteeingthat the installation load curvecan be monitored accurately and theobjective cos φ can be attained.Measurement and compensationCIRCUTOR's vast range of regulatorshas been designed to cover the compensationrequirements in each differenttype of installation.In order to compensate installationswith quick load variations, CIRCU-TOR's fast series computers must beused, since they are capable of compensatingthe reactive consumption inmilliseconds (ms).In unbalanced systems, if you wish toinstall a conventional regulator that willmeasure a single phase, you run therisk of insufficient or excessive compensations.CIRCUTOR has designedthe computer plus series to compensateunbalanced installations. Computerplus is available in the plus-Tversion (contactor switching) and Plus-TF version (thyristor switching), whichare capable of compensating the totalreactive consumption in real time andphase-by-phase.Computer Plus is an innovative productthat offers a wide range of newcharacteristics, three-phase measurements,phase-by-phase compensation,built-in power analyzer, test function,protection against harmonics, leakage,control, communications, etc. This catalogueincludes additional informationabout our new product.The following example shows how theunbalance between phases can becalculated in a percentage and how todetermine the need to perform a compensationprocess with a three-phasemeasurement using the Plus system.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 choosewhether our capacitor bank will havea three or single-phase measurement,within a 12% unbalance in one of thephases.The previous example shows that L1and L3 are above 12% of the unbalance,so the use of computer Plus isrequired.R1-3
