Abstract :
Laws of occurrence of breakdowns of vacuum interrupters behind front of a lightning impulse at recession of voltage (overdue delayed breakdowns) are experimentally investigated and the hypothesis of their nature is developed. It is shown, that the reason of breakdowns is the high-voltage discharge on an internal surface of insulating cases of vacuum interrupter.
