HP & LP speed in GE gas turbine

CSA. Apr 24, 2014. #2. Hi GE, HP and LP refer to ''High-Pressure'' and ''Low-Pressure'' shafts, and speeds. The pressures are "relative" pressures, one turbine operating at a higher pressure than the other, which is called the "low pressure" turbine (shaft). Some GE-design gas turbines have multiple shafts that spin at independent speeds.
