An example measurement is shown in Fig. 3.12, where the evolution of different temperatures as a
function of time can be seen. In this test recirculating chiller (constant cooling liquid temperature 25 °C)
was applied and both the cables and the camera were insulated.

It is important to note that the results are indicative and valid only for the described test setup. The length
of insulation was less than 1 m and there was no heat load from arc process.
