Abstract

PURPOSE: To eliminate the adoption of the measured result of other preventive diagnosing item in the operating state of switches as preventive diagnosed result by sorting the diagnosing item into a diagnosing item for preventively diagnosing only when the switches are operating and a diagnosing item of other functions.
CONSTITUTION: The outputs of sensors 17-1W17-n are converted into electric signals through electric signal processors 18-1W18-n, respectively. Then, the signals are sorted into a group A (item for diagnosing insulation, conduction, gas characteristics) and a group B (item for diagnosing opening or closing of the switches), and applied to a cutout circuit 20 consisting of gates of logic elements 21. The respective signals are applied through the gates 20 to a general diagnosing circuit 21. The diagnosed result from the circuit 21 is applied to a data output circuit 24, which has a display unit 25 and a printer 26.
