Electrical measurement and controlMeasurement Transformers and ShuntsThe concern to measure the installation'sconsumption or any electrical parameterduring the energy management procedureshas arisen with the need to transformhigh currents into small currentsthat can be measured by electronic units.CIRCUTOR offers a solution with a vastrange of transformers with different featuresthat can cater for the main marketneeds.M.7DefinitionCIRCUTOR's current transformershave the following features:}}1. Insulation and separation of circuitsand measurement devices fromthe voltage lines.}}2. Prevention of alterations generatedby the transmission of high currents.}}3. Reduction of short-circuit currentsto admissible values in measurementdevices.}}4. Obtaining currents that are proportionalto those measured, so that theycan be transmitted to the appropriatedevices.Selecting a transformer1. Know the features of the work environmentor operating conditions (indoor,outdoor, maximum operating temperature,etc.)}}2. Know the features of the line whereit will be installed:Cable or busbar dimensions• xMeasurement margin of the currentbeing measured (maximum andminimum current)Overload (range andtime).• xNetwork voltage (low, medium or highvoltage)• xShort-circuit current}}Grid frequency3. Know the featuresof the associated instrument (accuracy,nominal current, consumption, etc.)}}4. Know the distance between thetransformer and instrument, as well asthe section of the cable used for theconnection.Transformer powerPower is a very important parameterthat must be taken into account. In atransformer, the primary current mustinduce the necessary power in the secondarycurrent in order to transmit it tothe measurement unit. Induced powermust be equal to or more than the linelosses plus the power consumed by themeasurement equipment, in order to ensurethat it can operate correctly.Line losses (P L) are expressed as thepower losses caused by heating duringthe transmission of current through thecircuit cabling resistance (R L) of the secondarytransformer, i.e., the resistanceof the cable between the transformerand the unit.P L= R L·I 2Where: R Lis inversely proportional to thediameter's square and is proportional tothe cabling length ( one way+return).M7-3

Measurement Transformers and ShuntsTransformer saturationA transformer will become saturatedwhen its primary current or load areabove the nominal values.The linearity of the current transformationbetween the primary and secondarydecreases, so that the error can bequite high. The saturation of the transformeris inversely proportional to theload. (See Fig.1)In the case of current transformers,they are saturated by overloads in orderto make sure that the equipment isnot damaged from the secondary. TheF sparameter (Safety Factor) showsthe number of primary current transmissionsthe transformer is capable oftransferring to the measurement equipmentbefore it is saturated.ApplicationsFig.1, Graph I p/ I sConverting a high nominal current to alower current so that it can be measuredby the unit.Here are some examples of applicationsthat use CIRCUTOR's transformers:}}Applications with TC + CVMk2 transformers:The busbar or cable can be disconnectedto insert the transformer.}}Applications with TP + CVM Minitransformers:The busbar or cable can not be disconnectedto insert the transformer.}}Applications with shunts + MK-DC:To measure electrical parameters in aDC installation.M7-5

Measurement Transformers and ShuntsCurrent transformersSTPSplit-core current transformerDescriptionSplit-core current transformers of small dimensionshelps to save time to electrical installatorsduring the mounting process. Thistype of current transformer helps to measurein panels where there is not enough spaceto place an standard CT. Moreover, thanks toits split-core it’s possible to measure currentwithout disconnecting the power supply.Primary ranges goes from 100 A up to 300 Awith a maximum diametre of 23 mm.FeaturesMain featuresPrimary current (depending on the model)Secundary current100-125-150-200-250-300 A/1 AApplicationWhen it’s necessary to make a temporarymeasure in an electrical facility, it’s very importantto save time during installation process.STP current transformers allows tomesure energy being used with Circutorpower analyzers or energy meters withoutpower supply disconnection.Split-core allows to measure in small sizepanels and helps to provide a solution withless space.I minFrecuencyIsolation voltageHighest voltage for the caseAdmisible overload0,01 x I n50 / 60 Hz0,72 kV3 kV 1 minute1.2 times x I nWorking temperature -20 ºC ... +55 ºCSF 2,5Protection levelBipolar 6.5 V pType of encapsulationCAT III 600 V ACOutput terminals2 x M3 with terminal coverStandardsIEC-60044-1, IEC-61010-1DimensionsReferencesType A Class V·A internal (mm) CodeSTP-30 100/1 3 1 23,4 x 24 M73303001125/1 3 1 23,4 x 24 M73304001150/1 3 1 23,4 x 24 M73305001200/1 1 0,5 23,4 x 24 M73306001250/1 1 1 23,4 x 24 M73307001300/1 1 1,5 23,4 x 24 M73308001(mm)M7-18

Measurement Transformers and ShuntsTransformers used to increase the impedanceTE seriesTransformer used to increase the impedanceDescription}}Accuracy class 1}}Power 15 V·AApplicationFor applications where the measurement unit can not be installed nearthe measurement transformer and, as a consequence, the distancebetween both is longer. The problem lies in the fact that increasingthe distance increases the number of losses caused by the overheatingof the cable and in some cases the unit might not take readingsaccurately. With this unit at the transformer's output and another unitat the input of the measurement device we can increase the distancebetween both without so many power losses.ReferencesCurrent ratio Type Code5 / 0.1 A TE - 5 / 0.1 M70911Current adding transformersTSR SeriesCurrent adding transformers, fixed ona DIN railDescription}}Accuracy class 0.5}}Power 15 V·A}}The transformers added must have the same ratio}}No input must be without a connection}}Transformer certificate sheet is attachedReferencesN. o of inputs Type CodeApplicationUsed to add the current to various AC electrical lines to obtain acommon output current that is proportional to the sum of all currents.The current of various lines can be measured in a singleunit.2 x 5 A TSR-2 M707013 x 5 A TSR-3 M707024 x 5 A TSR-4 M707035 x 5 A TSR-5 M70704M7-32
