The degradation of insulation systems is a complex physical process, many parameters act at the same time thus making the interpretation extremely difficult. The insulation is very much responsive in transformer serving closer to design life. Strategic maintenance and operational procedures are best formulated where the condition of existing unit has been accurately assessed. To facilitate asset management...
This paper present the transformer design optimization problem. The objective of transformer design optimization problem requires to minimizing the total mass (or cost) of the core and wire material by satisfying constraints imposed by international standards and transformer user specification. The constraints include appropriate limits on efficiency, voltage regulation, temperature rise, no-load...
Power transformers being the major apparatus in a power system, thus the assessment of transformer operating condition and lifespan have obtained crucial significance in latest years. Dissolved gas analysis (DGA) is a sensitive and reliable technique for the detection of incipient fault condition within oil-immersed transformers, which provides the basis of diagnostic evaluation of equipment health...
Incipient fault diagnosis of a power transformer is greatly influenced by the condition assessment of its insulation system specifically oil/paper insulation. In recent times, a number of intelligent methods based on AI techniques, Artificial Neural Network and Fuzzy Logic have been used to predict incipient faults in a power transformer based on its insulation studies under various kinds of stresses...
