FIELD: electrical engineering.
SUBSTANCE: for determination of the network zero-sequence circuit parameters the transitory process free component is used carrying complete information on the circuit proper frequency and goodness and isolated from the neutral offset voltage; for generation of a pedestal current pulse within the network circuit a source with low installed capacity is used in high on-line time ratio mode. This method ensures the required accuracy of setting to any specified compensation mode within the whole range of the ground-fault neutraliser inductance adjustment, inter alia - in networks with combined neutral grounding. It involves no limitations as to the type of the ground-fault neutraliser applied.
EFFECT: setting accuracy enhancement and reduction of equipment installed capacity.
