      <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>
