Opis:: The paper presents results of research works whose aim was to determine and indicate characteristics of optical signals emitted by corona discharges occurring in the vicinity of two types of high-voltage (HV) cap insulators. The experimental studies were performed under laboratory conditions using an ultraviolet (UV) camera. Two types of cap insulators were analyzed: one made of glass and the second one made of porcelain. For both considered insulating devices, the influence of supply voltage on the intensity of optical radiation was determined. The obtained results were analyzed and compared. Based on the results, it was stated that both cap insulators indicated similar characteristics but the most significant difference lied in the existence of the punch-through on the glass cap.

Opis:: 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.
