Rogowski current measurement

November 2015 Electrical Power & Protection

OSI of the USA now offers Rogowski-based high current AC measurement systems.

The CTRS family is capable of measuring from 1 to 40 kA utilising a Rogowski head which will fit busbars or bus tubes from 165 to 540 mm Ø. The signal from the Rogowski head is processed by an integrator, and industry standard outputs of 0-5 V DC, 0-10 V DC, 0-1 mA DC and 4-20 mA DC are available. Instrument power of 115/230 V AC is required. Accuracy is ±1% with a linearity of ±0,25%. As there is no iron core, installation is simplified for applications where space is at a premium.
