| Abstract: | Aimed at the special feature of dry LV reactor fault caused by fire and creeping discharge on reactor surface, the thermal aging test of material, determination of temperature rise in normal condition, and overvoltage during switching operation were carried out. Inspection of disassembled failured reactor and discharging mark on material, the cause of reactor fault is revealed and remedy proposed. |
| Keywords: | dry reactor insulating material temperature rise aging |
