Hydraulic machines - Acceptance tests of small hydroelectric installations
IEC 62006:2010 defines the test, the measuring methods and the contractual guarantee conditions for field acceptance tests of the generating machinery in small hydroelectric power installations. It applies to installations containing impulse or reaction turbines with unit power up to about 15 MW and reference diameter of about 3 m. The driven generator can be of synchronous or asynchronous type. This International Standard contains information about most of the tests required for acceptance of the hydraulic turbine such as safety approval tests, trial operating and reliability tests, as well for verification of cavitation, noise and vibration conditions, if required. This standard represents the typical methods used on smaller hydroelectric installations, and is divided into three classes as follows: Class A: Default, normal test program (panel measurement), to determine the maximum output of the installation. Class B: Recommended, extended test program, to determine the performance characteristics of the installation. Class C: Optional, comprehensive test program, to determine the absolute efficiency of the installation. All classes contain safety tests, trial operating tests, and reliability tests. This standard gives all necessary references for the contract in order to execute the test, evaluate, calculate and compare the result to the guarantee for all the classes A, B and C.

Machines hydrauliques - Essais de réception des petits aménagements hydroélectriques
La CEI 62006:2010 définit les essais, les méthodes de mesure et les conditions de garantie contractuelles relatifs aux essais de réception sur site des machines générant l'énergie dans les petits aménagements hydroélectriques. Elle s'applique aux installations comportant des turbines à impulsion ou à réaction d'une puissance allant jusqu'à 15 MW environ et d'un diamètre de référence de 3 m environ. Le générateur peut être de type synchrone ou asynchrone. La présente Norme internationale contient des informations relatives à la plupart des essais requis pour la réception des turbines hydrauliques tels que les essais pour approuver la sécurité, les essais de fonctionnement et de fiabilité, ainsi que les essais de vérification des conditions de cavitation, de bruit et de vibration, s'ils sont exigés. La présente norme présente les méthodes types utilisées pour les petits aménagements hydroélectriques, et se divise en trois classes, comme suit: Classe A: Par défaut, programme d'essai normal (relevés sur le panneau de contrôle), pour déterminer la puissance maximale fournie par l'installation. Classe B: Recommandé, programme d'essai étendu, pour déterminer les caractéristiques de l'aménagement en matière de performances. Classe C: Optionnel, programme d'essai complet. Pour déterminer le rendement absolu de l'aménagement. Toutes les classes comportent des essais de sécurité, des essais de fonctionnement et des essais de fiabilité. La présente norme fournit toutes les références nécessaires au contrat afin de réaliser l'essai, d'évaluer, de calculer et de comparer le résultat par rapport à la garantie pour toutes les classes: A, B et C.
Vodni stroji - Prevzemni preskusi majhnih hidroelektrarn (IEC 62006:2010)
Ta mednarodni standard določa preskus, metode merjenja in pogoje pogodbene garancije za terenske prevzemne preskuse generatorskih strojev v majhnih hidroelektrarnah. Velja za inštalacije, ki vsebujejo impulzne ali reakcijske turbine z močjo enote do približno 15 MW in referenčnim premerom približno 3 m. Gnani generator je lahko sinhronega ali asinhronega tipa. Ta mednarodni standard vsebuje informacije o večini preskusov, zahtevanih za odobritev vodne turbine, kot so odobritveni preskusi varnosti, preskusi za preskusno delovanje in zanesljivost, ter za potrditev kavitacije ter pogojev hrupa in vibracij, če je potrebno. Ta standard predstavlja običajne metode, uporabljene pri manjših hidroelektričnih inštalacijah, in je razdeljen v naslednje tri razrede (glej preglednico 1 za podrobnejši opis):
OPOMBA: Vsi razredi vsebujejo preskuse varnosti, preskuse poskusnega delovanja in preskuse zanesljivosti. Ta standard podaja vsa potrebna sklicevanja za pogodbo, da se izvedejo preskusi, da se ocenijo, izračunajo in primerjajo rezultati pri garanciji za vse razrede A, B in C. Proizvajalec ali svetovalni inženir je odgovoren za zagotavljanja, da so vgrajene standardizirane povezave za izvedbo teh preskusov. Ta standard ne zajema podrobnosti o strukturi hidroelektričnih inštalacij ali njihovih sestavnih delov.
