Rogowski coil SN140

SN140-CAT-PI2-SN140
Rogowski Coil SN140 (7 mm cross section) is a flexible current transducer based on Rogowski principle. SN140 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. SN140 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. SN140 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. Class 0.5-A1 according to IEC 61869-10.
