Abstract: The disclosure relates to electrical machine condition monitoring by placement of a Fibre Bragg Grating (FBG) in the stator of an electrical machine. Example embodiments include an electrical machine comprising: a stator having a plurality of stator teeth having windings around each tooth; a rotor rotatably mounted within the stator; and an optical fibre mounted to the stator, wherein the optical fibre comprises a Fibre Bragg Grating, FBG, positioned between an adjacent pair of stator teeth and oriented to measure a tangential strain between the pair of stator teeth.

Abstract: Cladding of the interior of a component part of a pressure vessel is shown. A lining which conforms to at least a portion of the interior geometry of the component is positioned in the interior of the component. The lining is then pressed into the component past its yield strength. The lining is then fused to the component.
