CSN® Air-Coil

The CSN® Air-Coil is a special design based on the physical construction of a Rogowski Coil.

Due to the iron-free design the coil does not have any saturation which allows to use only one CSN® Air-Coil Module for both metering and protection arrays. Additionally the CSN® Air-coil 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® Air-Coil Modules are combinable and hence the output voltage level is adjustable to customer request.

The very compact design with an excellent long-term stability are additional benefits for special applications.
