LEM has announced the introduction of the first AC current sensor family based on patent pending ‘Perfect Loop’ technology. After calibration, the new RT series achieves absolute accuracy of better than 0,65% – including position error - making these split-core Rogowski coils suitable for use in Class 1 power devices.
An imperfect coil structure induces an unbalanced geometry and increases sensitivity to the position of the measured conductor within the sensor, or to the proximity of external electric cables. The RT series overcomes the problem of asymmetry resulting from the discontinuity at the sensor opening, which is inherent in conventional split-core Rogowski coils. Whilst other manufacturers use complex and costly clasp designs to minimise the effects of discontinuity, LEM engineers have invented a unique magnetic coupling technology that allows a perfect extension of the magnetic flux at the loop opening which compensates for coil asymmetry. In addition, LEM has developed an advanced coil-winding process which produces exceptionally regular windings, to further enhance sensor symmetry, accuracy and immunity to electromagnetic interference.
The 5 mm gauge RT sensors are currently available with sensing apertures with diameters of 55 mm or 125 mm and have a five-year guarantee.
