To ensure the safe and reliable operation of oil-immersed transformers, real-time monitoring of them is necessary. The main contents of operation monitoring include parameters such as the oil temperature, winding temperature, oil level, load current and voltage of the transformer. Through the monitoring devices such as thermometers, oil level gauges, ammeters and voltmeters installed on the transformer, these parameters são transmitidos em tempo real para o sistema de monitoramento . O pessoal operacional pode entender imediatamente o status operacional do transformador com base nesses parâmetros e lidar com quaisquer situações anormais em tempo hábil .
