(if present)
- For an more accurate measurement, place the cable conductor in a central
position with reference to the ring
- For a correct measurement, calibrate the Rogowski’s coil: write the calibration
coefficient to the corresponding Modbus register (refer to the user manual) or set it
using the menu on the display (see display programming manual).
Example: if the Rogowski’s coil feature is 90 mV / 1000 A, set the tarature register
(corresponding to the phase where the Rogowski’s coil is applied) with the value:
1000 / (90 · 10).
NOTE ABOUT ACCURACY
: The device is provided with 0.5% accuracy.
Global accuracy is the sum between the device accuracy and the connected
Rogowski’s coil accuracy.
