A sensing device () for a high voltage disconnecting switch (). The sensing device () comprises: a first optical fiber () configured to receive light from an optical source () and configured to guide the light; an optical collimator () coupled to the first optical fiber () to receive the light guided in the first optical fiber () and configured to collimate the light into a collimated light beam; a bendable optical component () coupled to the optical collimator () to receive the collimated light beam and configured to guide the collimated light beam, wherein the bendable optical component () is configured and arranged to bend depending on a switching state of the high voltage disconnecting switch (), thereby influencing the collimated light beam; and a deriving unit () configured to derive information about the switching state of the high voltage disconnecting switch () based on the collimated light beam.

Sensing device

The invention relates to a method and device for fiber optic temperature measurement. The invention also relates to a multimode quartz glass fiber with nanocomposite (NK) containing a polymer and quantum dots (QDs) and its manufacture. These are based on temperature-dependent emission of quantum dots on the surface of optical fibers.
