Art - passive Rogowski coils with very high accuracy

A flexible Rogowski coil with a spindle core dedicated to AC measurements in which galvanic separation between the high-current circuit and the measuring system is required. The use of the patented Perfekt Loop technology allowed to significantly reduce the measurement error resulting from the position of the primary conductor inside the instrument's loop, as well as errors resulting from the influence of external fields.

Features
  • Rated insulation voltage 1000 V Cat III PD2
  • Accuracy Class 0,5 (IEC 61869-2)
  • Protection degree IP67
  • Ø70, Ø125, Ø175, Ø300 mm sensing aperture
  • 1.5 m output cable (other lengths available on request)
  • Ambient temperature −40 °C … +80 °C
  • Very flexible and thin coil: 6.1 mm
  • Slot for attaching the loop on the primary with a cable tie
  • Ø2 mm hole to pass a security seal tampering
  • An innovative patented clasp drastically reduces the positioning error near the closing
  • Internal shield for enhanced measurement accuracy at low primary currents.
 

Advantages

  • Thin, flexible, and light weight solution
  • Very low positioning error
  • Quick, non-intrusive and easy setup
  • A single sensor for a large current range without overload
  • Less influenced by external fields
  • Adaptable for a large range of cable diameters.

Standards

  • IEC 61010-1: 2010; IEC 61010-2-32 ed.3: 2012
  • 1) IEC 61869-1 ed1.0: 2007; IEC 61869-2: ed1.0: 2012
  • 1) IEC 61869-6: draft 2016; IEC 61869-10: draft 2016
  • UL (pending)
