The system of protection of the frequency-controlled drive from TEEMP as an insurance against accidents and losses.
Today, frequency-controlled drives have become very widespread in the industry, since the economic effect of their installation is noticeable almost immediately. For example, feed pumps with FCD (frequency-controlled drive) at a power plant can save up to 30% of electricity by regulating the speed of the engine, also reducing water losses by up to 10%. For a submersible pump for oil production, the repair interval increases by 3-4 times. This is important, given the complexity and cost of extracting it from the well.
