RS 3P
Three Phase Rogowski Coil Current Transformer
Input current range 0 to 10000 A
Output 0.333 Vac, 100 mV per 1000 A, or 0 to 5 Vac
Product Range
Flexible Rogowski Coil Current Transformers
Air cored rope style coils that clip around irregular bus, cable bundles and awkward geometry. 10 A to 100 kA, coil length 20 cm to 200 cm, mV or integrated 0-5 V output, bandwidth 2 Hz to 100 kHz, accuracy 1.0.
What Problem This Range Solves
Iron cored CTs saturate, weigh too much and simply will not fit around a laminated bus run or a bundle of parallel cables. A Rogowski coil has no magnetic core, so it does not saturate, weighs almost nothing and bends into the space that exists.
Who It Is For
- Power quality and harmonic analysis instrument makers
- Switchgear retrofit and arc flash protection projects
- Generator, UPS and large drive monitoring
- Test and measurement equipment OEMs
Key Benefits
- No magnetic core, therefore no saturation at fault current levels
- Fits irregular bus, cable bundles and space limited panels
- Coil size chosen independently of the primary current rating
- Installed on a live conductor without disconnection
