Abstract
A method of manufacturing an electromagnetic induction device with On-Load Tap Changer. The method includes: a) providing an electromagnetic core with windings, b) suspending an OLTC insulation barrier from the electromagnetic induction device by a suspension, wherein the OLTC interface barrier arrangement is arranged to act as a barrier between an electromagnetic core housing and an OLTC, and wherein the OLTC interface barrier arrangement is provided with a first set of electrical connections arranged to be connected to the windings and a second set of electrical connections arranged to be connected to the OLTC, c) connecting the first set of electrical connections to the windings, and d) subjecting the windings and the OLTC interface barrier arrangement to a drying process.
