      <abstract xml:lang="ru">
        <p>Как известно, наиболее простым и удобным методом проверки тяговых двигателей, работающих на открытых горных разработках, является метод, основанный на определении нагрева двигателя по среднеквадратичному (эффективному) току. Знание эффективного тока электровозов кроме того необходимо для ряда расчетов, связанных с электрификацией карьерного железнодорожного транспорта: для определения потерь энергии в электрической схеме электровоза, потерь энергии в контактной сети и т. п.</p>

        <p>As it is known, the simplest and most convenient method of testing traction motors operating in open-pit mining is the method based on determining the motor heating by the RMS (effective) current. Knowledge of the effective current of electric locomotives is also necessary for a number of calculations related to the electrification of quarry railway transportation: to determine the energy losses in the electric circuit of the electric locomotive, energy losses in the contact network, etc.</p>
