PECULIARITIES OF CALCULATION OF MAGNETIC SYSTEMS WITH SHORT-CIRCUITED SECONDARY WINDINGS IN IN-PLANE FORMULATION
Introduction. A feature of quasi-static calculation of plane electromagnetic fields is unlimited volume occupied by the current. This condition imposes certain requirements on the choice of boundary conditions for solving such problems (the vanishing of the algebraic sum of the currents flowing thro...

В статье анализируются проблема, связанная с вопросами корректного задания первичных источников токов и ошибок в определении параметров вторичных короткозамкнутых контуров при решении задач плоскопараллельного поля. Приводятся физический и математический анализ ошибки и предложен способ решения подобных задач на примере расчета трансформатора тока и электромагнита переменного тока. У статті аналізуються проблема, пов'язана з питаннями коректного завдання первинних джерел струмів і помилок у визначенні параметрів вторинних короткозамкнених контурів при вирішенні задач плоскопараллельного поля. Наводяться фізичний і математичний аналіз помилки та запропоновано спосіб вирішення подібних завдань на прикладі розрахунку трансформатора струму і електромагніту змінного струму.
