Description : What is the generator IR value when generator is filled with stator water and hydrogen?
Last Answer : Generator IR when filled with stator water and hydrogen is about 100 kΩ only. That is because most of the gases and liquids are self-restoring insulators. As we are measuring insulation with 1 kV or 5 kV ... region moderate voltage (1 kV to 70 kV), and breakdown region is above 70 kV voltage.
Description : When the hydrogen explosion will take place in main generator?
Last Answer : When hydrogen concentration in air is more than 4% and less than 74% causes the explosion.
Description : What is used to purge hydrogen from the generator casing?
Last Answer : During generator purging CO2 is used to purge out H2 from the casing.
