Abstract
The invention, which relates to an arrangement for current measurement at a current lead-through, addresses the problem of specifying an arrangement for current measurement by means of which a reliable, galvanically isolated measurement of motor phase currents can be carried out, wherein the space requirement of the arrangement is reduced. This problem is resolved thereby that the sensor is a measuring coil and that the measuring coil is disposed on the lead-through contact such that it is galvanically isolated from the same.
