Assessment of power transformer conditions and lifespan has acquired crucial significance in latest years. Dissolved Gas Analysis (DGA) has proved to be useful for diagnostic of incipient and potential faults in power transformers. The first part of this paper deals with an experimental investigation carried out to study relation between gas generation and partial discharge. In the second part, a fuzzy logic based interpretation method (FL1), which is founded on fuzzy set theory is described and implemented as an improved DGA interpretation method that provides higher reliability and precision of fault diagnostics.
