Abstract

A coil winding consisting of an electrical conductor (1) provided with an insulation is monitored using an optical waveguide (2) for the purpose of a distributed temperature measurement. The electrical conductor (1) has a longitudinal groove (3) on one inner side below the insulation. The optical waveguide (2) lies loosely in the longitudinal groove (3). In addition, the optical waveguide (2) is longer than the electrical conductor (1) by an amount which is sufficient to ensure that it is protected from excessive elongation in the event of a large degree of thermal expansion of the electrical conductor (1). In a method for manufacturing the coil winding, the conductor combination of electrical conductor (1) and optical waveguide (2) is first wound on an auxiliary drum (5). The coil winding is then wound in an opposing winding direction. <IMAGE>
