FIELD: electricity.
SUBSTANCE: method is based on detection of pre-breakdown events (PE), such as occurrences, changes of shape and volume of gas bubbles, charged moles, micelles - "dark formations" on electrode surfaces. Based on information of a laser beam reflected from the electrode surface, images are created, which are compared in time, the previous one with the next one. Images recognition is self-tuned for two signals - "no breakdown anticipated" and "breakdown expected". The more frequently such events occur, the faster the breakdown will happen - a signal "equipment needs repair" is generated, which may be used to organise a preventive repair with specification of repair areas on images of working electrodes.
EFFECT: reliability improvement.
