The Rogowski coil is used for measuring AC currents and is primarily employed for particularly simple retrofitting in existing installations with a choice of either on busbars or on power cables. The output signal from a Rogowski coil differs from that issued from a conventional current transformer. This must be noted upon connection. Janitza provides Rogowski coils that can be used together with a measurement transducer as well as Rogowski coils which are suitable for direct connection to suitable measurement devices.
