Abstract: The actual and theoretical power consumption of ESP was calculated and analyzed. The result shows that the operational power consumption of ESP can be classified into effective power consumption, non-effective power consumption and adversely effective power consumption. The pulsed energy-saving and power supply technology was developed to reduce non-effective and adversely effective power consumption greatly, improve power utilization efficiency and realize the energy-saving operation of ESP. This technology was widely verified in many industrial applications.

Key words: ESP, energy saving and efficiency increasing, power supply control, power consumption, back corona
