It is common for power plants to regard the difference between high-and low-voltage sides as power loss to roughly determine operation status of main transformers.But this approximation is inadequate to reflect actual status when the calculated loss becomes abnormally high under the interference of other factors.This paper reports the treat-ment for the abnormal high-to-low-voltage side electricity measurement difference encountered by an actual main trans-former.By performing the comprehensive examination,and combining on-site conditions with electric test data of relevant equipment,historical data and curves were analyzed and the cause of the anomaly was identified,thereby successfully sol-ving the operation troubles.It also proposes measures to reduce comprehensive internal power consumption for plants.
