要約(英語): To understand the electrical properties influenced by water absorption, the space charge measurement was performed for an epoxy (EP) / Boron nitride (BN) insulating composite that is expected to be applied as a higher thermal conductive insulating material. The negative space charge in absorbed EP/BN composite without silicone oil was observed just after the voltage application, and the negative charge amount in the vicinity of the anode increased with the increase of the time. On the other hand, the homo space charge in absorbed EP/BN composite with silicone oil was observed just after the voltage application and the distribution is the almost same until 600 s after the voltage application. The OH- content near the anode after the voltage application in absorbed EP/BN composite without silicone oil was also larger than that before the voltage application while the OH- content near the anode after the voltage application in absorbed EP/BN composite with silicone oil was smaller than that before the voltage application. The intermittent water pass over the electrodes caused by the addition of silicone oil led to the fixed space charge profiles in absorbed EP/BN composite with silicone oil.
