Summary

IS 6966 covers field acceptance testing of hydraulic turbines at hydroelectric power plants — efficiency, cavitation, and vibration verification.

Methods for field performance testing and acceptance of hydraulic turbines — efficiency, cavitation, vibration.

Key Values
Francis turbine efficiency90-95%
Kaplan turbine efficiency88-93%
Practical Notes
! Thermodynamic method is most accurate for efficiency (±0.2%).
! Test at multiple gate openings for full efficiency curve.
