NRC series
Ø8 screw type flexible Rogowski coil

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.

Advantage        

* Excellent linearity
* Wide dynamic range
* Not damaged by large overloads
* Excellent degree of rejection to the

external current conductor
* No danger from open-circuited

secondary
* Zero power consumption
* Small position error
* Soft and light, easy to install
* Long-term stability
* Wide dynamic range
* IP68 protection level

 

* Applications

* Smart meter
* Rectifier current measurement
* Power quality analysis
* Motor overload/short circuit protection
* Current monitoring of power frequency and intermediate

frequency welding machine
* Medium and high voltage switchgear protection system
* Remote Terminal Unit (RTU)
* Synchronous Phasor Measurement Unit (PMU)
* Current measurement on the secondary side of the

electric furnace
