Compensation of earth fault current and reactive power

The need to compensate for the earth fault current has increased as a result of increased cabling. Compared to overhead lines, underground cables generate approximately 40 times higher earth fault currents. The increase in the cabling of the 20 kV distribution network also causes new challenges concerning reactive power, as the underground cable generates more reactive power than the overhead line. To meet these challenges, we provide compensation projects with the customer's desired configurations. We also offer compensation batteries for the needs of production equipment.
