<p>PURPOSE:To suitably and rapidly cope with a gas insulated apparatus by standardizing a discharge potential from various types of timing transfer pattern, the continuity of a partial discharge and the timing characteristic of a discharging charge amount. CONSTITUTION:Detector groups for obtaining timing transfer information including a partial discharge detector 5a are provided outside a sealed vessel 2. The groups has a partial discharge detector 5a, an acoustic detector 5b, a temperature detector 5c, a snowfall detector 20a, an earthquake detector 20b and a switch opening/closing operation detector 20c. These groups are connected to a diagnosing device 6 through A/D converters 10a-10c, 30a-30c. The device 6 standardizes the generating position of the partial discharge from the timing transfer pattern, the continuity of the partial discharge and the timing characteristic of the discharging charge amount to be judged on the basis of signals obtained from the detector groups.</p> |
