ESCT-RC series are flexible current transducers based on Rogowski principle, particularly suitable for measurement in combination with portable devices. ESCT-RC 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 its size and 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. ESCT-RC series 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 portable 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 our measurement by all applictions.
