Summary:The development of condition evaluation for power transformer maintenance are presented in this paper. The techniques consist of three types: electrical test, insulating oil test and visual inspection, which is considered by 21 test methods: Dissolved Gas Analysis, Load History, Power Factor, Thermo Scan, Oil Quality, Furan, General Condition, Bushing, Surge Arrester, Conservator Tank, Main Tank, Hot Line Oil Filter, Radiator and Cooling System, Transformer Control Cabinet, Neutral Ground Reactor (NGR), Protection Equipment, Regulating PT, OLTC Compartment, OLTC Control Cabinet, DGA of OLTC, and OLTC Oil Quality. The condition assessment for transformer is performed by the analysis of each method, indicated by scoring and weighting factor of each tests. This method with further development could be used to effectively plan the maintenance of power transformer.
