Determining the boundaries of the zone of optimal values of the voltage which circuit for step-down transformers
Abstract
Considered the definition of the boundaries of the zone of voltage values to. Z. Permissible under the terms of the electrodynamic and thermal stability of the transformer and the requirements of the electrical network. The conformity of the standard values of the voltage k is estimated. H. transformers with capacity from 40 to 25 000 kVa voltage classes from 6 to 110 kV are optimal values and recommendations are given on how to change this value in some types of transformers.
