Indications can include altered vibrations, rising bearing or winding temperatures, unusual noises, electrical deviations, or recurring fault messages. However, a single symptom does not allow for a definitive diagnosis. We compare operating data, measurements, and maintenance history to narrow down mechanical, electrical, and control-related causes.

Inspections, measurements, bearing and carbon work, as well as certain mechanical or electrical measures, may be possible depending on the system and the findings on site. Extensive winding work, deep disassembly, or testing under controlled workshop conditions generally indicate the need for removal. We jointly assess accessibility, occupational safety, lifting and transport concepts, the extent of damage, and the necessary testing equipment.

A reliable diagnosis before a shutdown clarifies the scope of work, spare parts, personnel, and required lifting or transport equipment. Critical components can be procured or prepared early, and work steps can be planned in parallel. We coordinate on-site work, workshop activities, and inspections. While unknown findings cannot be completely ruled out, their impact on downtime can be significantly reduced.

Important information includes the plant and generator type, fault and event logs, trend data, existing measurements, and current photos. We also require details on access, nacelle, lifting options, safety regulations, location, and the planned work window. Weather and logistical conditions can also affect the operation. This information allows us to prepare the team, measuring equipment, spare parts, and any necessary follow-up work effectively.

We combine trend data, fault logs, inspection findings, and maintenance history with the criticality of the affected components. This results in a binding basic scope as well as pre-defined options for findings that only become apparent after disassembly. Spare parts, personnel, lifting equipment, and testing can thus be prepared in stages.
