The Rogowski coil is a current transducer that permits
measurement of current in a conductor up to 2000A. The coil
is not a fixed closed loop, the end is looped about the conductor
and parked in the fitting at the base of the loop.
Method C is frequently used without problems, method D is
however the preferred method of use.
The Rogowski coil lends itself perfectly to being fixed round
irregular shaped objects, including fuse assemblies, in difficult-to-access
locations. The loop is normally hung over the conductor for
temporary or permanent current measurement.
The Squirrel logger input includes an integrator that
dispenses with the need for an external device, providing a cost effective and
compact measuring system. The coil is independent of frequency.
