A wide range of rugged clip around flexible coil current probes using Rogowski Coil technology for wide bandwidth measurement and faithful conversion of current to voltage, intended for use with oscilloscopes, data loggers, transient recorders, power meters and power analyzers.   Based on the Rogowski principle, these probes yield very high bandwidth performance and measurement of very high currents (10A-300kA).  The small coil profile (typically 8mm dia), means the coil can be retrospectively installed without disruption to an active power system.  As standard, the coil is insulated at 10kVrms, insulation can be increased if required.   Models are available with a variety of clip-around coil sizes to suit most conductors, allowing easy current monitoring even where access is limited.
