Interface quasi‐distributed fibre Bragg grating positioning detection of glaze icing load on composite insulators

The electrical performance of transmission line insulators will decrease dramatically under ice-covered conditions, and ice flashover may occur operating voltage. There is no direct effective monitoring method for cover on lines. In this paper, the interface quasi-distributed fibre Bragg grating (FBG) used to study positioning detection glaze icing loads composite insulators, a mechanical lever model single load umbrella with three FBGs established. Based model, multi-glaze location multiple skirts proposed. Six optical fibres 13 each are implanted into 110 kV insulator. minimum test FBG detecting load, axial/circumferential sensing rule glaze, weight simulation laboratory verification multi-glazes multi-umbrellas carried out. results show that simulated by weights accurate, in basically correct.
