Electrodynamic Withstand of Power Transformers to Short-Circuit Currents
The analysis of simplified expressions allows us to estimate the electrodynamic withstand of power transformers to short-circuit currents on power electrical station and substation. Examples of calculations of magnetic field induction, mechanical forces and pressures that determine the electrodynamic withstand of electrical equipment are given. Simplified qualitative calculations allow us to assess the impact of key parameters on the selection of appropriate elements and the possible range of their changes during the design, operation and modernization at the preliminary design stage.
