CJSC �lnas-Volga�has been working in the ESPU (Electric Submersible Pump Units for oil production) servicing market in Russia and abroad since 2001.Power of electric motor is up to 1000 kWt, Voltage is from 0,4 kV up to 3,0 kV.Nowadays frequency converters of different models and manufacturers are using for electric drive control. So, frequency converters are usually the reason of losses of power quality, and this fact is, in its turn, the cause of service interruption and fail of technical equipment.Our aim is using Active and Passive harmonic filters for high harmonic compensation in network to provide the high operating time of Pumps and Asynchronous Motors.
