4. This question is about transformer heatinga) Choose three different transformer protection devices. Give an advantage anda disadvantage of using each one.b) Look at FIG 1, which is the heating curves for a 600 kVA transformer. Copy itand mark on it for your answer.i) Identify the safe continuous temperature for this machineii) How long would it take for the transformer temperature to rise by 50°C if itwere running at 750 kVA?iii) If the ambient temperature were lower, what would happen to the
