Abstract (en)
[origin: WO2017077379A1] A current transformer for measurement of a high voltage power line (12) comprising an openable magnetisable ring core (13) comprising a plurality of iron strips encircling the power line and a secondary winding (9) for sensing a current in relation to the current of the high voltage power line. The core (13) comprises overlapping ends (17a, 17b) having an overlapping area (14), and the core receives high voltage potential.
