RogoTrans Rogowski Transducer

Rogowski coil – thinner, lighter ex converter for simple installation

The Rogowski coil is used for current measurement of AC currents and is primarily employed for retrospective installation in existing systems - optionally on power rails or power cables. Retrospective installation around the primary conductor is possible, because the Rogowski coil can be separated. The output signal from the Rogowski coil is fed to a measurement transducer, which issues standardised AC current of max. 1 A at the output.

• Frequency bandwidth of the Rogowski coil 50/60 Hz, up to 700 kHz without load (no-load operation)
• Accuracy per class 0.5, in accordance with IEC 61869
• Operating temperature: -40°C to +80°C
• Rated insulation voltage 1kV CATIII
• Rogowski coil from 10 to 10000 ARMS – in combination with Janitza measurement transducer RogoTrans up to 4000 ARMS
• Accuracy better than 0.65 % irrespective of the position of the primary conductor
• Sealing possible
• CE-certified (2014/30/EU), in accordance with the European Directive 2014/35/EU and tested in accordance with the standard IEC 61010-1
• Unique, IP67, exible and precise AC current transformer with separating core, based on Rogowski coil technology
• Retrospective clip-on system without disconnecting the phase conductor
• Device for xing to the primary conductor with a cable tie
• Internal screening
• High linearity, no saturation, no current upper limit of the Rogowski coil

The measurement transducer for the Rogowski current transformer RogoTrans measures alternating currents and possesses a standardised output signal of 0 to 1 A. The metering range is up to 4000 A, the voltage supply is 24 V DC. The measurement transducer is very compact by design and can be mounted on a DIN rail.
