Product Description SRC ?12 High Sensitivity Flexible Rogowski coilHigh linearity from 1A to 100kAWide dynamic rangeVery useful with large size or awkward shaped conductors or in places with limited accessNo danger from open-circuited secondaryNot damaged by large overloadsNon-intrusive, no power drawn from the mainMeasurement uniformity at any position of the conductor inside the coilExcellent degree of rejection to the external current conductor IP65 protecting level.FeatureSRC is a flexible current transducer based on Rogowski principle, particularly suitable for measurement in combination with portable devices. SRC coils are available in different sizes and can be supplied according to customer's design, therefore they can be used in all those applications, in which traditional transducers are not fitting due to its size and/or weight.Due to its specific features, flexible Rogowski coil is an extremely confortable solution for current measurement and can be used in a number of cases where traditional current transducer is not the adequate solution.SRC coil is provided with a shield against the influence of external magnetic fields, therefore it grants a stable measurement from low currents to hundreds of kA. The Rogowski coils must be connected to an electronic integrator for 90° phase shift compensation and frequency equalization. Our DIN-RAIL and panel meters can interface Rogowski coils directly without the need of the external integrators. This is an advantage because there is no external boxes or any power supply with consequent ease of use. The particular features of the Rogowski coils combined with the extremely flexible input programming of our portable meters, allow to carry out measurement by all applications. Advantage?

Power meter,Power analyzer sensor What is a Rogowski coil?Rogowski coils have been used for the detection and measurement of electric currents for decades. They are based on a simple principle: an "air-cored" coil is placed around the conductor in a toroidal fashion and the magnetic field produced by the current induces a voltage in the coil. The voltage output is proportional to the rate of change of current. This voltage is integrated, thus producing an output proportional to the current.By using precision winding techniques, especially developed for the purpose, the coils are manufactured so that their output is not influenced by the position of the conductor within the toroid, and to reject interference from external magnetic fields caused, for example, from nearby conductors.Basically, a Rogowski coil current measuring system consists of a combination of a coil and conditioning electronics.Rogowski coil current transducers are used for the AC measurement.They can be used in similar circumstances to current transformers but for many applications they have considerable advantages:? Wide dynamic range.? High linearity.? Very useful with large size or awkward shaped conductors or in places with limited access. Thanks to the structure without hard core, the coil can be easily manufactured according to the application or to the available space.? Unlike traditional current transducers, there is no danger from open-circuited secondaries.? They cannot be damaged by large overloads.? They are non-intrusive. They draw no power from the main circuit carrying the current to be measured.? They are also light weighted and in some applications are light enough to be suspended on the conductor being measured.The transducer does not measure direct currents but, unlike a current transformer, it can carry out accurate measurements of AC component even if there is a large superimposed DC component, since there is no iron core causing saturation. This feature is particularly useful for measuring ripple currents for example in battery charging systems.Specification MODELSRC-50SRC-100SRC-150Coil length180mm380mm555mmWindow size50mm100mm150mmCoil Resistance 255 (+/-10) Ω375 (+/-10) Ω540 (+/-10) ΩReference Rated current≤500kAWeight100-500gRatioCalibrated333mV/kA@50HzUncalibrated360mV/kA@50HzRead AccuracyCalibrated <0.5% (central position, 25oC) Uncalibrated < 5% tolerance (central position, 25oC)Maximum current measurable 500kACoil Section12mmLead length2meterTemperatureUncalibrated 200ppm/CCalibrated 300ppm/CPosition Error±1% maximumOutput on 0A (zero drift)≤0.05mVPhase error≤0.5°Linearity±0.2% of readingBandwidth1Hz to 100kHz(-3dB)Operating temperature-40oC to 80oCStorage temperature-50oC to 90oCFor other requirements, please contact us for customization.Position sensitivityConductor PositionTypical Error(%)Adjacent to the center of coil <0.5%Adjacent to the inside of coil<1%Materials Coil & cableThermoplastic rubberflame retardant UL 94 V-0 ratedCouplingsPP Flame-RetardantColor(coil)Orange,GreyShielded100% coil, 100% output cableSafety Certifications CE markedComplies with LVD EN 61010-1:2010EMC EN 61326-1:2013IP65 Voltage insulationCoil: 2000VSignal cable:1000VSafety1000V CATIII ,600V CATIVDimensions tolerance:A,B,C,F:±5mm, D:±0.2mm,E:±10mm Dimensions(mm)SRC-50SRC-100SRC-150A.Windows size A80115175B.Windows size B50100150C.Coil O.D.104139199D.Coil section12E.Lead Cable Total Length2000F:Coil length275380550More Special Rogowski coil+Integrator for fault indicatorRogowski coil NZ special for high temperature electric furnaceRogowski Coil Sensor for Lightning currentSafety and warning notesIn order to guarantee safe operation of the transducer and to be able to make proper use of all features and functions, please read these instructions thoroughly!
