WCT

Welding machine Rogowski coil


High linearity from 1A to 100kA

Wide dynamic range

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

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.
