Application

Modern power plant generators turbo generators, and turbine generators as used in power stations, produce a great deal of heat which must be dissipated. The preferred method of cooling is hydrogen cooling which has a cooling capacity of around seven times that of ambient air. It is essential that the hydrogen remains uncontaminated by air leakage or a potentially explosive gas mixture can result. Air in-leakage also increases the viscosity of the hydrogen and therefore its friction with the rotor, increasing the losses within the system. Before either filling with hydrogen or re-filling with air, it is necessary to use an inert intermediary gas to avoid creating a flammable mixture. Carbon Dioxide (CO2) is the gas most commonly used for this. Thus, for filling the generator, air is first purged from the system with CO2 and then the CO2 is purged out with hydrogen. The Alternator Purge Gas Monitor measures all stages of the hydrogen filling and air re-filling processes as well as the hydrogen purity during normal operation.
