An oil temperature indicator continuously measures top-oil temperature, which reflects internal thermal stress. It provides alarms and trip signals when preset temperature limits are exceeded, helping prevent insulation damage, accelerated oil aging, and catastrophic failures caused by overheating or cooling system malfunction.
