Studyweb Generator Hydrogen Cooling Generator hydrogen cooling. state the purpose of the generator hydrogen cooling system. name the advantages and disadvantages of hydrogen as a generator coolant. describe how the tcv for the hydrogen coolers is operated at sequoyah. describe the operation of the generator leak detectors. name all equipment in the secondary reducing station. State the required generator hydrogen pressure before stator coolant is placed in service and how we monitor whether or not generator gas pressure is higher than stator coolant inlet pressure generator must be > 45 psig to run stator cooling water system.
Generator Hydrogen Cooling System Youtube 99%. =((0.99*1) (0.01*14.4))*100. because air is 14 times as dense as hydrogen, the density of the fluid in the generator casing rises quickly with air impurity level. as can be seen from the equation, every 1 percent of air contamination is worth about 14% increase in fluid density. increased fluid density means increased windage loss. This drawing shows the unit 1 generator field (1935) which is air cooled; in 1943 hydrogen cooling became practical, which reduced the field size by about 30%. Csa. feb 25, 2010. #2. the concepts of a hydrogen cooled generator are very simple. as current flows in a conductor, heat is generated. a generator has a lot of conductors and a lot of current flowing through the conductors, generating a lot of heat. if that heat isn't "removed" then the windings will be damaged (insulation "blisters. Many power generators over 150 mw in capacity utilize hydrogen as a cooling method to transfer heat from the power generating winding enclosure to the heat exchanges known as h2 coolers. hydrogen cooled power generators are more efficient and have less mass of materials of construction than their air cooled cousins.
