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.
