FIELD: electricity.
SUBSTANCE: invention relates to training of vacuum arc-quenching chambers of high voltage by pulse discharges of high voltage of various polarity after chamber tapping, which is performed as charge of not more than 10 microcoulomb for each of discharges passes through trained gap.
EFFECT: invention provides for high electric strength of vacuum arc-quenching chamber of high voltage due to reduction of changes on surface of contacts at arc stage of pulse discharge.
