Rogowski Coil MFC150 (8 mm cross section) is a flexible current transducer based on Rogowski principle. MFC150 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.
MFC150 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. Our power meters UPM209 and UPM309 can interface Rogowski coils directly without the need of the external integrators (Smart kits). This is an advantage because there is no external boxes or any power supply with consequent ease of use.
MFC150 can be also provided with built-in integrator, without needing of external devices for 90° phase shift compensation and frequency equalization. This is an advantage because there is no external box with consequent ease of use. Our power meters UPM209 and UPM309 can interface Rogowski coils directly without the need of the external integrators (Smart kits).
