The ESCT-RC series consists of flexible current transformers based on the Rogowski principle. ESCT-RC coils come in various sizes and are used in many different applications where traditional transformers are not suitable due to their size and/or weight. Due to its specific characteristics, the flexible Rogowski coil is an extremely convenient solution for current measurement and can be used in several cases where a traditional current transformer is not the ultimate solution. The ESCT-RC series is equipped with protection against external magnetic field interference, providing stable measurements from low currents to hundreds of kA.
