Opis:
Solar blind UV cameras are not theoretically supposed to be sensitive to solar light. However, there is practically always some sensitivity to solar light. This limited solar sensitivity can sometimes make it impossible to detect the weak emission of a corona target located on the solar background. Therefore, solar sensitivity is one of the crucial performance parameters of solar blind UV cameras. However, despite its importance, the problem of determining solar sensitivity of solar blind UV cameras has not been analysed and solved in the specialized literature, so far. This paper presents the concept (definition, measurement method, test equipment, interpretation of results) of measuring solar sensitivity of solar blind UV cameras.

Opis:
Solar-blind ultraviolet cameras with image intensifier with CMOS detector typically use various count methodologies to measure the optical energy of an electrical corona. However, these count methodologies are non-radiometric without considering parameters such as distance, focus-, zoom-, and gain setting of a camera. An algorithm which considers the calibration and radiometric measurement of optical energy for the slow frame rate intensifier type cameras is presented. Furthermore, it is shown how these calibration data together with the flowcharts are used for the conversion from raw measured data to radiometric energy values.

Opis:
Solar-blind ultraviolet cameras as part of high-voltage electrical inspections until recently have mostly been used for pure observations. These observations only imply the presence of corona discharges and not the severity thereof. A radiometric algorithm together with a calibration algorithm to perform an optical energy measurement were presented earlier. This is a guide on how to apply the algorithm to determine the total optical measurement from corona discharges, plus additional processing. This guide and additions are used to compare the electrical and optical domains with actual examples. The main objective is to illustrate how to determine the electrical and optical relation for the IEC 60720 high-voltage electrical test configurations using a standard open procedure.
