Figure. 5.3.21 - 167. Thermal image response with nominal load (installation according to presumptions).
As the results show, the end temperature of 68.39
̊
C is reached when the cable is loaded with a stable
current for time equalling five times the time constant τ. This uses approximately 71 % of the thermal
capacity. According to the datasheet, this current should set the temperature around 65
̊
C; therefore,
the model overprotects by three degrees.
