適用范圍：1.1.1 This guide applies to any type of reaction or impulse turbine. as well to any type ofpump-turbine and storage pump, coupled to an electric generator or motor.1.1.2 The guide covers the field ofvibration and pulsation tests referred to as standard tests.The objectives ofthe tests are as follows:Assessment of hydraulic machine design: manufacture and quality of erection from theviewpoint ofvibration**.Assessment ofthe changes of vibration behaviour during the machine life.Provision of recommendations applying to operation of unit (for instance, choice of themost appropriate transient sequences).Aid in analysing faults and break downs.1.1.3 If it is not possible to apply the recommendations ofthe guide because ofthe construction ofthe hydraulic machine. or if it is not necessary to conduct some of the measurements, suchitems may be omitted on prior agreement between the manufacturer and the user.
