Title:
METHOD OF DETECTING ABNORMAL CONDITIONS IN GAS-INSULATED POWER APPARATUS
Document Type and Number:
Japanese Patent JP2010206963
Kind Code:
A
Abstract:
To improve gas separation performance by simplifying a separating operation while eliminating the necessity of large scale facility.
An adsorbent 4 taken out (step S1) from a gas-insulated power apparatus to be detected is allowed to contact a liquid more easily adsorbable than a decomposition gas of an insulation gas (step S2), thereby analyzing a gas emitted from the adsorbent 4 into the liquid (step S3) to detect abnormal conditions in the gas-insulated power apparatus based on the detection of the decomposition gas (steps S4-S6).
