The earth fault state balancing of the electricity distribution networks is covered by capacitive earth fault current compensating devices. The correct compensation contribute to fast arc quenching, surface voltage gradient decrease. Moreover there is certain possibility to keep the network in operation. The aim of the paper is to propound the theoretical background of the resonance earthing, the characteristics of Petersen coil circuit and case study of diagnostic measurements for the coil status assessment.

PL

W bilansie prądów zwarciowych doziemnych trzeba uwzględniać pojemnościowy prąd doziemny urządzeń kompensujących. Przy prawidłowej kompensacji i szybkim gaszeniu łuków powierzchniowy gradient napięcia maleje. Celem pracy jest przedstawienie podstaw teoretycznych rezonansowego doziemienia, charakterystyki obwodu cewki Petersena i diagnostyki stanu cewki.
