ART Series

Unique, IP57, flexible split-core AC current sensor implementing high accuracy Rogowski Coil technology.

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 circuit (power) and the secondary circuit (measurement). The patented Perfect Loop Technology dramatically 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. 

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

ART rogowski coil current sensors

Main characteristics

  • Class accuracy 0.5 according to IEC 61869
