l Excellent degree of rejection to the external current conductor
Feature
RCT is a rigid current transducer based on Rogowski principle, particularly suitable for measurement in combination with portable devices. RCT coils are limited in different sizes but competitive cost,therefore they can be used in fixed application like power distribution box.
RCT 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 is 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.
