CSN® Air-coil

The CSN® AirCoil is a special design based on the physical construction of a Rogowski Coil. Due to the ironfree design the coil does not have any saturation which allows to use only one CSN® AirCoil Module for both metering and protection arrays. Additionally the CSN® Aircoil shows linear transmission behaviour over a wide frequency range. A current range of hundred amperes up to several hundreds kiloamperes is easy to realize. CSN® AirCoil Modules are combinable and hence the output voltage level is adjustable to customer request. The very compact design with an excellent longterm stability are additional benefits for special applications. Further information about our CSN® AirCoil
