Flexible Split Rogowski Coil and Voltage Integrator

Split-Core Rogowski Coil Current Sensor Application: The JRF MOI PU Flexible, Split-core, Rogowski Coil current sensors are incorporated with products used for the measurement of AC current and DC current pulses. The flexible, split-core design permits the installation on odd shaped primary conductors and BUS bars while the conductor is “live“. The Rogowski Coil current sense principle offers significant advantages over standard magnetic core current transformer products:
Features:
  • Voltage integrator incorporated as part of the sensor “yoke”.
  • Single sensor loop, capable of accommodating a range of primary conductor sizes.
  • Characterized by high sensitivity, accuracy, linearity, minimum phase shift.
  • Suitable for harsh operating environments (temperature, humidity, EMI).
Specifications:
  • Current Range: 250A to 6,000A
  • Input Frequency: 50/ 60Hz
  • Accuracy: < 1%
  • Phase Shift: < 0.5 degrees at 50/60Hz/li>
  • Linearity: ±0.2% from 2% to 120% of rated primary current
  • Primary Conductor Position Sensitivity: ± 1% maximum
  • Influence of External Field: ± 1.5% maximum
  • Operating temperature: -25ºC to +65ºC
  • CE Approved
  • RoHS Compliant
