It is comparable to the cost of the necessary investment for the purchase of a transformer. Current transformers and other electrical equipment no longer refers to the lifetime of the equipment, but rather depends on the reliability of the equipment itself. With reference to the reliability of the transformer, surely it takes care and maintenance to ensure that the transformer a transformer is in good condition and reliable enough to operate. The methods of the DGA (Dissolved Gas Analysis) is one of the types of care and maintenance is needed to indicate the reliability of the transformer by means of measuring the concentration of dissolved gases in transformer oil. The DGA testing has become a method of regular maintenance performed on the transformer. The DGA testing serves a simple analysis to predict the disorders pushed his gas dissolved. By measuring the concentration of dissolved gases through testing the DGA can give us an idea of what happens on the transformer.In General, the DGA testing can also present a prediction about the condition and reliability of the transformer.} }
