The optimal current measuring method for retrofitting for space-saving energy data acquisition: The 855 Series Rogowski coils can be easily retrofitted in existing systems and above all, without interrupting ongoing process. With this technology, there are no saturation effects, i.e., Rogowski coils can measure a wide primary current range without loss of accuracy. Modern production methods allow accuracy class 1 acc. EN 61869 and make the comparison between coil and measuring instrument obsolete.
Wide temperature range and high rated insulation voltage
The high rated insulation voltages of 1,000 V Cat. III/600 V Cat. IV and the available coil diameter of 70, 125 and 175 mm make new installation options possible. Signal lines of 1.5 and 4.5 m avoid costly and signal-altering extensions. Further technical refinements such as mounting brackets for fixation with cable ties, the sealable bayonet catch and wide temperature range of -40 °C …. +80 °C guarantee safe and easy handling.

The Functionality of Rogowski Coils
The Rogowski coil is placed around a conductor or current bar. The AC current flowing through the conductor induces a proportional voltage in the Rogowski coil.
