Easy and safe installation
Easy installation in a confined space
Simply place the handy Rogowski coil quickly around power rails and circular conductors.
Acquire alternating currents up to 4000 A AC with the universal current measuring system.
Benefit from fast installation that does not require you to remove system parts.
Extra safety
Thanks to the Rogowski principle, no dangerous open circuit voltages can occur like with split core current transformers.
Highlights
- High system availability due to easy installation without removing system parts
- Transform alternating currents up to 4000 A using a single measuring system
- Space saving and handy: the current strength does not affect the size and weight of the coil
- Safe installation and operation: no dangerous open circuit voltages
- Harmonics and transients detected with phase accuracy with a large frequency range from 10 to 5000 Hz
- Rogowski coil secured on power rails and circular conductors, plus high measuring accuracy, thanks to professional holding device
