摘要

The aim of the research works, results of which are presented in this paper, was to determine the feasibility and to indicate the application scope of optical method in the diagnosis of high-voltage (HV) long rod insulators. Diagnosis of technical condition of HV insulators is critical, because the insulation system undergoes aging processes, which cause deterioration of the insulating properties. The measurements were performed during test under laboratory conditions using an UV camera. Corona partial discharges occurring on the long rod insulator were registered, while the supply voltage value was increased. The presented analyses consider dependencies of the supply voltage value on the count number of UV photons emitted by partial discharges occurring in long rod insulator made of porcelain.
