Abstract: An atmospheric corrosion sensor (1) for detecting corrosion of electrical equipment comprising at least two atmospheric corrosion sensing structures (Rs1, Rs2, Rs3) placed on at least one insulated corrosion sensor substrate wherein said corrosion sensing structures (Rs1, Rs2, Rs3) are accessible to corrosion atmosphere. Said atmospheric corrosion sensing structures (Rs1, Rs2, Rs3) have the same spatial dimensions and each of said atmospheric corrosion sensing structures (Rs1, Rs2, Rs3) comprises different composition of corrodible material.

Abstract: The invention reveals an atmospheric corrosion sensor (1) for detecting corrosion of electrical equipment due to corrosive gas comprising at least one atmospheric corrosion sensing structure (2) placed on at least one insulated corrosion sensor substrate (3) wherein said atmospheric corrosion sensor (1) comprises at least one gas permeable layer (4) placed on the corrosion sensing structure (2) wherein said gas permeable layer (4) allows for transferring the molecules of corrosive gases present in the atmosphere to the surface of the sensing structure (2), opposite to insulated corrosion sensor substrate (3), causing it to corrode.
