Reactive Power ControllerProduct descriptionIntended useThe reactive power controller Prophi together with externalcapacitor stages, serves for step by step controllingof the phase shift angle cos(phi) in 50/60Hz lowvoltage networks. Depending on the type of the reactivepower controllers Prophi, contactors or semi conductorswitches can be controlled directly.Additionally, the following electrical quantities are measuredand indicated:- Voltage L2-L3,- Current in L1,- Frequency,- Sum real power (Consumption/supply),- Sum reactive power (ind./cap.),- uneven current harmonic waves 1. - 19. in %,- uneven voltage harmonic waves 1. - 19. in %.The harmonic contents are related to the rated voltageor rated current.The connection is carried out on the back side via touchproof spring power terminals.Measurement and supply voltage are taken from themeasurement voltage and must be connected to thebuilding installation via a separation (switch or powerswitch) and an overcurrent protection (6,3A).The current measurement is carried out via a ../5A or../1A current transformer in one outer conductor.Hints for maintenanceBefore delivery the device is tested in various safetychecks and marked with a seal. If the device is opened,these checks must be repeated.There is no guarantee for devices, which are openedout of the manufacturing works.Repairing and calibrationRepairing and calibration work can be carried out in themanufacturing works only.Front foilThe cleaning of the front foil must be done with a softcloth using a common cleansing agent. Acid or acidicagents may not be used for cleaning.Waste managementThe device can be disposed as electronical waste accordingto the legal regulations and recycled.Data protectionThe data protection is carried out in a none volatilememory (EEPROM).Changed programming data are saved immediately.The relay outputs are suitable for contactor control, thetransistor outputs are provided for the control of fastswitching thyristor modules, switching at zero crossing.= Key 1 = Key 2 = Key 3Page 5

Reactive Power ControllerFunktional descriptionMeasurementThe measurement is suited for 3 phase systems with orwithout neutral conductor for frequencies of 50Hz or60Hz. The electronical measurement system records anddigitalizes the effective values of voltage between L2and L3 (L-N Option) and the current in L1.In each second several snap check measurements arecarried out. As the current is only measured in oneouter conductor, and the voltage only between two outerconductors, the measured values, which are related toall three outer conductors, are exact for equal loadedouter conductors only.The following electrical quantities are calculated:Current and current harmonicsVoltage and voltage harmonicsReal power, sumApparent power,sumReactive power, sumReactive power for each stageReactive current for each stageCos(phi),Net frequency.The following information can be indicated:Number of switchings of each stage,total connection time of each stage andthe inner temperature.Prophi measures the frequency of the measurement andsupply voltage and shows the average over 10 seconds.Switching of capacitor stagesProphi calculates the required reactive power to reachthe set target-cos(phi) from the current from one outerconductor and the voltage between two outer conductors.If the cos(phi) deviates from target cos(phi), externalcapacitor stages or transistor outputs are switchedon or off.In automatic mode the capacitor stages are switched inor off, when the required reactive power is higher orequal to the smallest stage power.If the power of the first capacitor stage is three times ashigh as the measured real power, all capacitor stagesare switched off.Switching outputsDepending on the variety of Prophi, relay or transistoroutputs serve as switching outputs.The relay outputs are suitable for controlling contactorsand the transistor outputs can switch thyristor modules,that switch in zero crossing of voltage.For relay outputs the time between two connections ordisconnections is set to two seconds. Transistor outputshave no limitation of the switching period.Net returnAfter net return, the set discharge time runs for therelay outputs. The transistor outputs do not mention thedischarge time.Page 6= Key 1 = Key 2 = Key 3

Reactive Power ControllerLearning of the configurationAfter installation of thecontroller there is thepossibility to learn andsave the configurationlearnwith the function"learn".Important requirements are:- The discharge time for capacitors is set to 60 seconds,when the device is delivered. For capacitors with longerdischarge times, the discharge time must be checkedand changed before using the "learn" function.- The current transformer must be flown through byconsumer and compensation current.- The measurement and supply voltage may not be takenfrom phase to N.- The compensation system must be ready for operation.The learning function of the controller is devided intotwo steps:Step 1 - Learning of the connection configurationHere the correction angle between current transformerand measurement and supply voltage is detected.Step 2 - Learning of the capacitor stagesHere the number of outputs and the stage power ofeach stage is detected.The following requirements are neccessary:- The switching of a capacitor stage must cause a changeof current of at least 50mA at current input.- The stage power of the stage to be learned must bebigger than 1% of the measuring range of the controller.Start learningGo to symbol learn usingkey 1.Select action (oFF, 1,2, 3) with key 3.learnStart learning with key1.The symbol learn flashes.

Reactive Power ControllerConnection configurationProphi can be deliveredin two connection varietiesfor the measurementand supply voltage.ProgIn the version measurement L-L, the measurement andsupply voltage must be taken from two outer conductors.In version measurement L-N, the measurementand supply voltage must be taken between outer conductorL and neutral N.Correction angleThe controller Prophi indicates the power factor, realand reactive power correctly, if current and voltage wereconnected according to the type plate and connectiondiagram. The phase shift between voltage and currentmust not be corrected, and the correction angle is 0°.The correction angle can be selected in the range of 0°- 359° in one degree steps.If the user cannot connect Prophi according to theconnection diagram, this can be corrected according tothe correction values of table 1 or 2.Devices for version L-N can be corrected with the correctionangles of table 1.Devices for version L-L can be corrected with the correctionangles of table 2.If the connection fault is not known, the correction anglecan be determined automatically by using the “learn”function.Example : Programming of the correction angleThe current transformer is installed in L2. "k-l" is notexchanged. The voltage measurement is done accordingto connection diagram between L2-L3.Table: Correction angleCurrent inVoltage betweenL1-L2 L2-L1 L2-L3 L3-L2 L3-L1 L1-L3L1 k-l 240° 60° 0° 180° 120° 300°l-k 60° 240° 180° 0° 300° 120°L2 k-l 120° 300° 240° 60° 0° 180°l-k 300° 120° 60° 240° 180° 0°L3 k-l 0° 180° 120° 300° 240° 60°l-k 180° 0° 300° 120° 60° 240°In that case you can read the angle of 240° in the table"correction angle".Confirm selection withkey 1.
