ESCT-RC150-3000A, Rogowski Coil, 150mm Diameter, 85mV/kA Rated for 3000 Amp Recommended, 3 Meter Cable length

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). 

Features

• Rated insulation voltage 1000 V Cat III PD2
• Accuracy Class 0.5 (IEC 61869-2)
• Protection degree IP67
  
• 3 m output cable (other lengths available see page 8)
• 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
  
• 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

Applications

• MV/LV substations on LV side: Transformer Condition Monitoring

Application Notes

1) The Rogowski coil can measure any primary current as there is no saturation effect.

2) Not tested given that in the worst case (load = 0 Ohm i.e. short circuit on the output) the peak dissipated power remains low (< 2 Watts)

3) Frequency bandwidth and phase shift modeling schematic can be provided on request.

4) Referring to the main phase offset of 90 ° (a Rogowski coil is a derivative current transducer)

5) Considering a primary conductor of at least ? 15 mm, perpendicular and in contact with the Rogowski coil.

6) Considering an external conductor of at least ? 15 mm the same current level than internal conductor, perpendicular and in contact with the Rogowski coil.
