Product Description

 

 

NRC series
Ø8 screw type flexible Rogowski coil Current sensor
The NRC series is a new generation of flexible Rogowski coil (Rogowski® coil) current sensors, which are especially suitable for measuring in combination with portable devices. NRC coils have different sizes to cope with different conductors. The new generation of NRC coil strengthens the shielding layer and greatly reduces the influence of external magnetic fields; it can be directly connected to our rail-mounted and panel-type meters without the need for external integrators. NRC series coils have IP68 protection grade, which is extremely suitable for outdoor use.
 

       Applications

1. Smart meter
2. Rectifier current measurement
3. Power quality analysis
4. Motor overload/short circuit protection
5. Current monitoring of power frequency and intermediate frequency welding machine
6. Medium and high voltage switchgear protection system
7. Remote Terminal Unit (RTU)
8. Synchronous Phasor Measurement Unit (PMU)
9. Current measurement on the secondary side of the electric furnace

      Advantage

1. Excellent linearity
2. Wide dynamic range
3. Not damaged by large overloads
4. Excellent degree of rejection to the external current conductor
5. No danger from open-circuited secondary
6. Zero power consumption
7. Small position error
8. Soft and light, easy to install
9. Long-term stability
10. Wide dynamic range
11. IP68 protection level
