Abstract:
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.
