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.
