Rogowski Coil Application Note (click here for pdf)

Flexible Rogowski Coils, such as the DENTInstruments 300A/3000A Flexible Current Transformer, are designed for easy placement around cable bundles, large bus bars and breaker panels. The position of the conductor in relation to the CT connector effects the overall accuracy of the CT readings. This application note shows optimal Flex Coil CT placement when installing around a conductor.

CT accuracy is usually calibrated with the conductor centered in the CT window. In practice the CT hangs on the conductor, as shown in figures 1 and 2, which can introduce measurement errors. Note that the error is greatest when the CT connector hangs on the conductor...
