: Measured for speed, position, and power.

It applies to electronic-hydraulic and mechanical-hydraulic governors used on conventional, constant-speed hydraulic turbines, including reaction, impulse, and pump turbines in generation mode. Current Status: Last reaffirmed in , it remains the active edition. The American Society of Mechanical Engineers - ASME Key Performance Characteristics Tested

Determination of full-rate servomotor timing and cushion time. Industry Importance and Compliance Asme Ptc 29-2005 -

Evaluation of the governing speedband and powerband.

For a complete evaluation of hydraulic turbine systems, this code is often used alongside others: : Measured for speed, position, and power

for one of the characteristics (like deadband or droop)

What distinguishes PTC 29-2005 from a simple operational guideline is its insistence on rigorous, repeatable test conditions. The standard mandates specific instrumentation accuracy, data acquisition rates, and boundary conditions (e.g., normal steam conditions, synchronized to a grid or operating in isolation). Key tests include: The American Society of Mechanical Engineers - ASME

However, as of 2025, no formal project committee has announced a new edition. Therefore, for hydraulic turbine speed governing tests.
