1. An apparatus for measuring a flow of current through at least one electrical conductor of an electrotechnical device which is disposed in a cooling channel, wherein a non-conductive cooling medium flows through the cooling channel during operation of the electrotechnical apparatus, the apparatus comprising:
a flux conductor which is disposed around the at least one electrical conductor; and
an evaluation circuit which is coupled to the flux conductor and is configured to determine the flow of current through the at least one electrical conductor by evaluating an electrical parameter of the flux conductor,
wherein at least a part of the flux conductor is disposed in the cooling channel.
