Connecting a frequency converter to control the performance of tank leveling pumps

This article is devoted to the use of soft starters and frequency converters for sewage pumping stations (SPS), as well as water pumping stations. A summary of the article can be seen in the picture below

With the transition to a market economy for companies, the problems of energy and resource saving have become of particular importance Prevention of unreasonable spending of money is now increasingly being solved with the support of high technologies,

An asynchronous electric motor is one of the key components in modern industrial and household systems. Its main function is to convert electrical energy into mechanical work. High reliability, simplicity of design, and cost-effectiveness have made this type of motor very popular. However, during its operation, certain challenges may arise, particularly high starting currents. When the motor is directly connected to the network, these currents can exceed the nominal value by 10–20 times. This creates a significant load on the electrical network and switching equipment, posing a risk of damage, especially with frequent starts or in the case of high-power motors.
