Abstract:
This paper presents a developed program by using an electrical test method for condition evaluation of power transformers to be able to know and assess the equipment operation and maintenance. Used in actual application, the thirteen transformers have rating of 550 kVA to 110 MVA at the voltage levels from 22 to 525 kV. Furthermore, three parts of power transformer considered to evaluate those conditions consist of Core, HV Winding and Bushing. Besides, weight and score criteria are used for evaluating the equipment performance. Finally, the sequent results of the condition evaluation of power transformers show out the developed program could effectively evaluate. Among those useful results, that can be applied to further planning and application
