摘要 A monitoring system for checking an electric rotary machine for local overheating including a sensing device for sensing the concentration of minuscule particles in a gas serving as coolant for the machine, and a supply device for supplying to the sensing device a test gas containing minuscule particles of gasifiable liquid. The test gas is supplied to the sensing device by the supply device to permit the sensing device to perform a sensing operation, so as to determine whether or not the sensing device is functioning normally.
