Abstract
The present invention relates to a static electric induction apparatus () comprising a winding () including a plurality of winding units (), at least one first spacer element () arranged between the winding units () and including a first groove () defined in the surface thereof, and a sensor system for monitoring the temperature in the apparatus, wherein the sensor system comprises an elongated and flexible temperature sensing element () disposed in the first groove. The first groove () has a curved part that receives the flexible temperature sensing element which is wound at least one revolution in the first groove (). The first groove enters and exits the first spacer element in one and the same end of the first spacer element. The apparatus comprises an elongated second spacer element () extending in an axial direction on the outside of the winding (). The second spacer element () comprises an elongated second groove () arranged in communication with the first groove, and the flexible temperature sensing element () is disposed in the first and second grooves.
