Transformer oil chromatographic analysis results to determine the operational status of the transformer

A variety of devices in the power system, transformers are expensive and important, which runs the state will have a direct impact on the safe operation of the system. For a long time, according to various offline preventive tests and transformer oil  mcb circuit breaker  analysis results to determine the operational status of the transformer, to a certain extent, can prevent accidents, but regular  power transformers  mechanisms and off-line test, however, exposed to the following questions: on the one hand blindly may be in a good condition for the regular maintenance of  electric meter , resulting in a waste of human and material resources; on the other hand, there are still some drawbacks due to equipment overhaul failed to discover and develop into a major failure is possible.
