PURPOSE: To determine the abnormal position of a gas insulating device in a wide range with less number of detectors by generating quasi-troubles at contacts in a state that a site installation is completed, and obtaining the relationship between the output patterns of the detectors and malfunction generating positions.
CONSTITUTION: In order to monitor the malfunction of a substation, detectors S1∼S8 are mounted at the ends of buses 601∼606. The output signals of the detectors S1∼S8 are simultaneously input to an input processor 10, and when no malfunction is recognized at the detection signals, an indicator 50 indicates the state. On the other hand, if a malfunction is indicted, a detection pattern 30 is detected, compared with a standard pattern 20 stored in advance, and the malfunction generating position and size are indicated on an indicator 50 by the pattern 20 having a most similarity.
