6 FAQs about [How to check leakage in the wind chamber of a generator]

What happens if a generator water cooled stator winding leaks?

Leaks in the generator water-cooled stator winding can affect machine availability and insulation life. The keys to minimizing the negative impact of a leak are early detection and timely repair. Routine leak testing of the stator winding is the best way to determine the existence of leaks.

How do you detect a leak in a winding?

To detect small leaks, the sniffer detector must be brought within 2 to 3 inches of the leak. Since it is nearly impossible to cover every square inch of the winding, tracer test techniques such as bagging the series loops, test only the most probable leak sites. This cannot provide confidence that the entire winding is leak-tight.

What are the common faults of a wind turbine generator?

Common faults of wind turbine generator. Generator electrical faults are mainly stator eccentricity, rotor eccentricity, broken rotor bars, and looseness. The main manifestations of generator stator faults are overheating of stator windings, insulation damage, and grounding.

What is a wind turbine generator failure analysis & fault diagnosis?

In this article, a comprehensive and up-to-date review of wind turbine generators failure analysis and fault diagnosis are presented. First, the electrical and mechanical failures of various WTG components, including stator, rotor, air gap, and bearings, are analyzed. Then, the fault characteristics and root causes of WTG are studied.

How accurate is a generator leak test?

In a typical test at 80 psi, a volume of 1.0 ft3 must leak out of the generator to register a change of 1 psi. For this reason, extremely accurate gages are needed, preferably with 0.1 psi indications. Also, to detect small leaks, the test must be done over many hours so that the leak volume becomes significant relative to the test’s sensi- tivity.

How do I know if my stator winding is leaking?

Routine leak testing of the stator winding is the best way to determine the existence of leaks. Leak tests, such as Vacuum and Pressure Decay tests, and use of the Stator Leak Monitoring System (SLMS), help detect larger leaks. A more sensitive test, such as Helium Tracer Gas Testing, is necessary to find smaller leaks.
