How a campaign runs

Instrument, acquire, analyze, report, recommend.

A repeatable sequence that turns an energized, spinning machine into a clear set of numbers and a decision you can stand behind.

/ 01

Instrument

Probes, keyphasors and references placed to the standard and the failure mode in question.

/ 02

Acquire

Synchronized data captured across every relevant operating point, no point skipped.

/ 03

Analyze

Synchronous vectors, spectra, orbits and trends resolved down to root cause.

/ 04

Report

A consolidated, figure-driven record traceable to the governing standard.

/ 05

Recommend

A clear path: accept, balance, correct or monitor — with the numbers to justify it.

On site

From the generator pit to the protection panel.

Electrical testing, machine-parameter determination and vibration diagnostics — wherever the unit is.

Selected achievements

A track record across North America's generating stations.

Commissioning, assessment and testing campaigns delivered for leading hydro and energy OEMs.
