Order now Distributor List Contact Sales INDOOR ROGOWSKI COIL FOR ELECTRONIC MEASUREMENT The ART series is an indoor flexible clip-around Rogowski coil for the electronic measurement of AC current with galvanic separation between the primary and the secondary circuit. The patented Perfect Loop Technology significantly reduces both the error due to the position of the measured conductor within the aperture, and the error due to the proximity of external conductors (X-talk). 

In addition, the ART series internal shield allows for an enhanced measurement accuracy at low primary current.

That Rogowski coil technology series of products are designed for both industrial and smart grid application domains.

ART Series - FEATURES AND BENEFITS Main characteristicsClass accuracy 0.5 according to IEC 61869Better than 0.75% accuracy regardless of the primary conductor’s positionRated insulation voltage 1kV CATIIIFrom 10 to 10000 A RMSThin, light and flexible split-core current sensor for easy installation anywhereAlmost perfect linearity, no saturation, no upper limit in current ratingInternal shieldLow output voltage proportional to the rate of change (derivative) of the primary current (electronic integrator required): 22.5 mV/kA @ 50HzFeatures6.1 mm gauge with sensing apertures of Ø 35mm to 300mmBandwidth: 50/60 Hz, up to 700kHz in open circuit condition (no load)Operating range: -40°C to +80°CFast clip-on mounting whilst cable is connectedSlot expected to fix the loop on conductor with a cable tieØ 2 mm hole to pass a security sealTypical applicationsSecondary distribution substationsDistribution transformer monitoringPhasor Measurement Units (PMU)Commercial and industrial buildingsMetering and sub-meteringDemand response (DR)Distribution system equipment 3 Phase Solutions for quicker installation Among the ART Series, three standout models feature an innovative integrated 3-coil design, delivering enhanced accuracy and robustness in a compact form:

ART-B22-D70-SP103ART-B22-D70-SP110ART-B22-D125-SP100Leveraging Perfect Loop Technology, these 3-in-1 Rogowski coils achieve Class 0.5 precision with minimal positioning error. 

Their overmolded interface, electrostatic shielding, and IP57 protection ensure reliable performance even in demanding environments. 

With connectivity options including RJ45 and Bulgin, and a placeholder for M12 integration, they’re ready to meet the evolving needs of modern energy monitoring systems.
