Abstract

A sensing system for detecting hydrogen in an insulation fluid (8) of an electrical device (10) is provided. The system comprises: a sensing element (15) which comprises an optically transparent substrate (20); a sensing layer (25) coated on the substrate, comprising a metal-comprising thin film which changes its transparency due to hydrogenation when exposed to a defined hydrogen concentration; a catalytic layer (30) adjacent to the sensing layer; and a permanent visual indicator (40) located adjacent to the substrate (20), such that the substrate is positioned in a line of sight between the permanent visual indicator (40) and an observer of the sensing system (1), such that the permanent visual indicator (40) becomes visible to an observer at a defined hydrogen concentration.
