The article presents summaries of works which have resulted in the presentation of a formula making it possible to determine an approximate transmittance of an IR window used in thermographic measurements of electric device temperatures. The equation was formulated after analysing components of the IR radiation reaching the camera lens in case when an IR window was not used and when an IR window was used. Conditions prevailing in course of the thermographic temperature measurement of electric devices contained in the switchgear were recreated in the performance of the works. The measurement system which was used in the experiment has been presented. Components of the IR radiation reaching the camera lens in case when the IR window was used and when the IR window was not used have been discussed. The obtained transmittance results of windows VPFR-75 FRK100-CL have been compared against data from literary sources.

The result of the works presented is the uncertainty budget of a thermographic temperature measurement taken through an IR window. The type B uncertainty determination method has been employed. Publication of European Accreditation EA-4/02 has been patterned. Conditions prevailing in course of the thermographic temperature measurement of low-voltage electric units contained in the switchgear were recreated as part of the works. The measurement system has been presented. Components of the infrared radiation reaching the camera lens in case when an IR window was used and when an IR window was not used have been discussed. Uncertainties estimated for the measurement done with an IR window and without an IR window have been compared.
