FIELD: electricity.
SUBSTANCE: neutral wire is earthed through in-series connected capacitance and resistance elements. Parameters of elements are chosen from conditions providing minimum offset voltage of neutral wire during damping of earthing arc. It is proposed to choose resistance of resistor is from range of 0.25 - 30 kOhm, and total capacitance of capacitors not less than 40 mcF.
EFFECT: improving reliability and safety of electrical supply network.
