Fexible Rogowski Coil Nrc Current Sensor

Product Description

NRC Ø8 Flexible Rogowski coil fixed by cable ties
High linearity from 1A to 100kA

Wide dynamic range

Very useful with large size or awkward shaped conductors or in places with limited access

No danger from open-circuited secondary

Not damaged by large overloads

Non-intrusive, no power drawn from the main

Measurement uniformity at any position of the conductor inside the coil

Excellent degree of rejection to the external current conductor

Feature:

NRC is a flexible current transducer based on Rogowski principle, particularly suitable for measurement in combination with portable devices. NRC coils are available in different sizes and can be supplied according to customer's design, therefore they can be used in all those applications, in which traditional transducers are not fitting due to its size and/or weight.
Due to its specific features, flexible Rogowski coil is an extremely comfortable solution for current measurement and can be used in a number of cases where traditional current transducer is not the adequate solution.
NRC coil is provided with a shield against the influence of external magnetic fields; therefore, it grants a stable measurement from low currents to hundreds of kA. The Rogowski coils must be connected to an electronic integrator for 90° phase shift compensation and frequency equalization. Our DIN-RAIL and panel meters can interface Rogowski coils directly without the need of the external integrators. This is an advantage because there are no external boxes or any power supply with consequent ease of use. The particular features of the Rogowski coils combined with the extremely flexible input programming of our portable meters, allow to carry out measurement by all applications.
