코로나 방전강도에 따른 UV센서의 자외선 검출감도 특성

In electrical power systems, any fault may cause the damages of power equipments and even leads to large area blackout. To avoid similar accident, it is important to periodically inspect whether the power equipment needs to be repaired or replaced. Inspections and diagnoses of corona discharges are important to prevent electrical faults of insulation in electrical power systems. In this paper, the characteristics of UV detection sensitivity of UV sensor according to the corona discharge intensity on the needle to planed electrode systems is studied.
