- Abstract
The paper presents measurements results of optical signals emitted by partial discharges (PD) occurring on various high voltage (HV) insulators made of porcelain. The following devices were considered during the research works: an insulating cylinder, a long rod insulator and a cap insulator. The optical signals were recorded with two different devices: 1) an ultraviolet (UV) camera and 2) a spectrophotometer. The measurements of optical signals were performed under laboratory conditions by changing the supply voltage and the distance between the HV and the ground electrodes. Based on the gathered results it was stated that the maximal number of optical emission counts, which was measured within the UV camera, was different for each of the considered device types. it was also stated that the optical signals registered with the UV camera (250-280 nm) are not the most intense signals contained in the radiation. Application of the spectrophotometer has enabled to show that there are more intense wavelength components which are in the range from 320-380 nm.
