4. Application/Mounting
4.1 Sensor Mounting
The Rogowski Coil/Current transformer should be mounted between the end termination and the point
where the cable screen is extracted. The CT may be mounted on the screened part of the cable. The
screen should then be fed back through the Rogowski Coil/CT to prevent earth fault currents or screen
transients exceeding the trip level setting and activating the indicator erroneously.
