摘要：
Insulation systems of windings for power transformers are influenced to the action of internal overvoltages generated during voltage tests and work of transformers in electrical power systems. Internal overvoltages in transformers are depended form protection characteristics of surge arresters its location, courses and maximal values of external overvoltages as well as the reaction of transformer to transient voltage at input clamps of windings. Simulations of overvoltages in transformers performed by use of the model with concentrated parameters of windings there are presented in the paper. Simplified results of calculations for overvoltages in transformer windings of different parameters and constructions there are shown. Simulations are compared to the results of investigations. (Simulations of overvoltages in windings of power transformers).
