Janitza
Rogowski current transformer
Highest measuring accuracy even with high or rapidly changing currents
The Rogowski coil is used to measure the current of AC currents and is primarily intended for retrofitting in existing systems. The output signal of the Rogowski coil is fed to a measuring transducer, which outputs a standardized AC current of max. 1 A at the output.
Technical data guaranteed only in combination with the Janitza RogoTrans measuring transducer 15.03.613
