  • The Effects of Hydrogen Sulfide Gas on Electrical Components

    The switchgear is located in a corrosive atmosphere that contains low concentrations of hydrogen sulfide (H 2 S) gas. At the time of the infrared survey, the air was tested inside of the motor control center (MCC) and showed the H 2 S gas concentration to be at 2.3 ppm. The presence of H 2 S gas played a significant role in the growth of the silver filaments on the breaker and the bus bar .
