Product Description NRC ?8 Flexible Rogowski coil fixed by cable tiesHigh 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 conductorFeature:NRC is a flexible current transducer based on Rogowski principle, particularly suitable for measurement in combination with portable devices. NRC 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 comfortable solution for current measurement and can be used in a number of cases where traditional current transducer is not the adequate solution.NRC 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 are 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.Specification:MODELNRC-100NRC-150NRC-200Coil length395mm525mm665mmWindow size100mm150mm200mmReferenceRated current1000A3000A6000AWeightApprox 100-120gRatioCalibrated85mV/kA@50Hz50mV/kA@50HzUncalibrated110mV/kA@50HzRead AccuracyCalibrated<0.5% (central position, 25oC) Uncalibrated < 5% tolerance (central position, 25oC)Maximum current measurable100kACoil Resistancefrom 100 to 250 ΩCoil Section8mmLead length TemperatureUncalibrated 200ppm/C2meterCalibrated 300ppm/CPosition Error±1% maximum Output on 0A (zero drift)≤0.05mVPhase error≤0.5°Linearity±0.2% of readingBandwidth1Hz to 100kHz(-3dB)Operating temperature-30oC to 80oCStorage temperature-40oC to 90oCOther requirements, please contact us to OEM.Company Information:Lonwow Industry Co., Ltd. is a leading manufacturer of electrical metal conduits and fittings in Jiangsu Province, China.
