Rogowski coil current transducers can measure alternating currents in a frequency range from less than 0.1Hz to several hundreds of kHz. Their measurement range is impressive ranging from a few milliamps to over 1 million amps. These transducers have an excellent transient response capability and they can be used for measurements on very large or unusually-shaped conductors. Rogowski coil technology offers solutions to today's and tomorrow's current-measuring problems.
Rocoil Limited, UK, is a Company which offers a design consultancy service based on experience of using Rogowski coils dating back to 1977. We export current-measuring systems to more than 40 countries worldwide and have a manufacturing capability for both prototypes and production runs.
