Abstract

The transformer is one of the most important and expensive components of the electric power system network. The major faults can cause damage to the power transformer, which are not only disturbing the electrical network, but also resulting in large losses. It is difficult to classify the incipient faults that occur in the power transformer if there is no suitable analysis being used. Deep studies about Dissolved Gas Analysis (DGA) found that Duval Triangle method and other techniques can be used to analyse the fault that will occur in the power transformer. Nowadays, Tenaga Nasional Berhad (TNB) is using Microsoft Excel software related to Duval Triangle method to analayze the power transformer. Research found that the Duval Triangle method of DGA gives the accurate result more than 88% compared to other techniques. Microsoft Excel is licensed software and the users need to buy at a high price to get the full licensed software. Java programming is used in the developing new Duval Triangle in Eclipse software. As the Eclipse software is open-source software and the licensed is free, therefore the license issue can be solved. The results from the new developed Duval Triangle software will be compared with the results from the existing software in order to proof that the new developed Duval Triangle software is valid to be used.
