40 Outage Solutions Outage Solutions Electro-Mechanical Testing Specialized tests for improved performance Global Repair Services Gas Turbine Repair Network Detect unusual situations with our specialized tests. These tests are typically recommended by Product Services to improve unit performance: Torsional testing determines resonant frequencies for torsional vibration. This test supports engineering to help ensure adequate separation between the rotor train and grid frequency. Acoustic testing measures sound pressure levels and analyzes spectral content to identify root causes of excessive machinery noise. Singular concentration produces standardized processes that increase efficiency, improve quality and cycle time, and result in better repairs. With GE s Center of Excellence (CoE) approach for repair services, we can concentrate our repairs resources to achieve consistent, high-quality results. At each CoE, our technicians receive specialized training, and we invest in specialized tooling and equipment. Each facility can then focus on specific areas of expertise, such as gas turbine power nozzles, buckets, shrouds, combustion, fuel nozzles and rotor hardware. Europe/Africa Middle East Asia Americas Generator endwinding vibration testing (Bump Test) determines if additional support is required for the endwindings. Operational Deflection Shape (ODS) modeling deduces the cause of excessive vibration and develops recommendations for resolution. A vibration survey is conducted to build a three-dimensional forced running shape model of the unit. Generator stator cooling water flow test (UT Flow) pinpoints individual bars with rates that are lower than average. Low flow can lead to higher stator bar temperature and accelerated ground wall insulation aging and an eventual forced outage. This test is performed during a major outage.
