Online Testing & Diagnostic Reports

Online testing services and diagnostic reports that provide the relevant information you need to plan maintenance ahead of machine failures.

Let us help you simplify assessment of your motors and generators so you can accurately prioritize your maintenance budgets on the critical machines before they fail.

Globally, we have field service and analytic teams ready to deploy in order to collect your machine condition data, interpret the results, flag the concerning machines and provide the likely failure mechanisms.

Iris Power can collect data, analyse the results and provide diagnostic reports providing you with the information you need to take corrective action through the following services:

Stator Partial Discharge Diagnostic Reports:

With 40% of your motor and generator failures being caused by stator winding insulation, regularly reviewing partial discharge monitoring results is a critical step for predicting machine failure.  Iris Power can performed partial discharge testing and reports on stator slot couplers (SSC), 80pF epoxy mica capacitors (EMC) and low frequency 1nF – 2nF couplers as required.

Rotor Magnetic Flux Diagnostic Reports:

Comprehensive rotor flux results can help avoid catastrophic in-service machine failures due to rotor position, shape deterioration and shorted pole turns.  Iris Power can collect, interpret and provide reports on Iris Power flux probes, and third party sensors, typically without adjusting generator operating conditions.

Stator End-Winding Vibration Diagnostic Reports:

Avoid phase-to-phase failures caused by fatigue fracturing of stator end-windings. End-winding vibration monitoring and analysis can detect loosening of stator windings and increasing vibration.   Iris Power can collect, interpret and provide reports on Iris Power fiber optic accelerometers and third party sensors.

Shaft Voltage and Current Diagnostic Reports:

Avoid bearing damage caused by current and sparking that causes pitting on bearings.  Shaft Voltage and Current trending analysis can identify when brush systems require adjustment or replacement prior to causing damage.

Air Gap and Vibration Analysis Diagnostic Reports

Air gap diagnostic reports can provide information on a wide range of generator problems such as stator core stability, stator frame stability, rotor stability, roundness and alignment issues.  Iris Power diagnostic reports can combine this information with machine load, temperature and process conditions to identify root causes of any air gap problems before costly damage.
