Reliability for Hydroelectric Generation

Turbine bearings, governor systems, and generator auxiliary equipment running for decades with limited maintenance windows. Armor distributes the contamination control and condition monitoring parts that keep capacity factor up.

Where Hydro reliability programs run into trouble

Three issues we hear most from hydro maintenance and reliability teams.

Moisture is constant

Powerhouse air is humid year-round. Reservoir breathers without desiccant let moisture into oil supplies, accelerating oxidation and rust.

Equipment outlasts spare-part chains

Plants from the 1960s and 70s are still operating on bearings whose original suppliers no longer exist. Replacement and re-spec is a quiet ongoing project.

Outage windows are tight

Annual or biennial outage windows are the only opportunity for major maintenance. Parts not on hand mean window slips.

Common questions

Do you carry breathers sized for large turbine reservoir tanks?

Yes. Breather capacity scales with reservoir volume and the breathing rate driven by thermal cycles and oil consumption. For multi-thousand-gallon reservoirs we typically spec manifold-mounted multi-breather assemblies — they handle the breathing volume that a single breather cannot. Send the reservoir capacity, oil type, and operating temperature swing and we will spec it.

Can you help spec retrofits on legacy equipment?

Yes. Send drawings or photos and we'll work with the manufacturer's catalog (or ours, when the OEM is no longer in business) to identify equivalents.

Plan your next outage parts list

Send your maintenance schedule and we'll quote in advance so the parts are on the dock before the unit comes offline.
