摘要：
Dry-type air-core reactor is a high-voltage equipment used in power system for current limiting, reactive power compensation and filtering, which often fails due to insulation aging in long-term operation, and among them the interturn short circuit fault rate is the highest. In this paper, an on-line monitoring device for dry-type air core reactor based on power angle is proposed. This device can realise data acquisition of multi-channel signals at the same time and achieve high-precision conversion. Finally, the power factor angle is obtained through data processing. The test results show that the device can effectively monitor the short-circuit insulation short-circuit fault of the reactor.
