| description | The choice evaluation between oil-immersed and drytype
transformers is often controlled by cost, location, and
application. This paper compares the electrical performance of liquidfilled
and dry-type transformers, which will assist the customer to
choose the right and efficient ones for particular applications. An
accurate assessment of the time-average flux density, electric field
intensity and voltage distribution in an oil-insulated and a dry-type
transformer have been computed and investigated. The detailed
transformer modeling and analysis has been carried out to determine
electrical parameter distributions. The models of oil-immersed and
dry-type transformers are developed and solved by using the finite
element method (FEM) to compare the electrical parameters. The
effects of non-uniform and non-coherent voltage gradient, flux
density and electric field distribution on the power losses and
insulation properties of transformers are studied in detail. The results
show that, for the same voltage and kilo-volt-ampere (kVA) rating,
oil-immersed transformers have better insulation properties and less
hysteresis losses than the dry-type. |
