摘要： In a gas cooled rotary electric machine using insulating coating material which is subjected to thermal-decomposition when the insulating coating material is exposed to high temperatures thereby generating submicron particles, the concentration in the cooling gas of submicron particles generated through thermal-decomposition of the insulating coating material and distributed in the cooling gas is detected and an alarm signal is issued when the time-integration of a signal representing the concentration of the submicron particles exceeds a predetermined reference integration value.
