Abstract
PURPOSE: To ensure monitoring of deterioration of hermetically closed insulating fluid from outside by detecting variation of physical quantity such as electric resistance of the material to be geverated through reaction with deteriorated products of insulating fluid.
CONSTITUTION: In the liquid phase of closed insulating liquid 2 including flon R-113, etc. is provided a deterioration detector 8 which consists of metals such as copper and silver and varies in physical quantities such as electric resistance through reaction of deteriorated products of fluid 2 such as chlorine compounds. By detecting resistance variations of this detector, it is possible to monitor the deterioration of closed insulating fluid from outside securely, as necessary.
