DETERMINATION OF VOLTAGE CONFORMITY FACTOR IN POWER SUPPLY SYSTEMS

New  technical  developments,  such  as  in  the  field  of  frequency  drives  of  technological  units,  electrified transport, wind, and solar power plants, apply devices built on the basis of powerful transistors. Modern devices designed on these elements  are  powerful  generators  of  higher  harmonics  of  currents  that  penetrate  the  grids  of  power  systems.  It  requires  the development of measures and means to limit the higher harmonics of currents in the electrical grids.
