PROBLEM TO BE SOLVED: To provide a transformer with a temperature monitor display unit having a function of retaining the highest temperature and the date of the operating state of the transformer. SOLUTION: In the temperature monitoring unit of the transformer, the monitor temperature and the date can be simultaneously recorded by digitizing a conventional temperature monitoring function. Moreover, this temperature monitoring function is performed by the temperature monitoring unit having the function of storing the past highest temperature and the date. Whether it exceeds the temperature rising limit of the transformer or not can be checked by reading these data, and the electric energy used of a load can be grasped. COPYRIGHT: (C)2005,JPO&NCIPI
