Vibration analysis involves recording vibration levels on critical equipment. By studying this information, we can detect potential bearing problems, misalignment in a motor, or other issues before they result in lost production.
At Harrison Electric, vibration analysis and testing is carried out by our category II vibration analyst, certified by the Vibration Institute in accordance with the requirements stated in ISO/FDIS 18436-2 vibration condition monitoring and diagnostics. Analysis includes both a written report and verbal consultation with recommendations.
When you open a panel, you never know what will be looking back at you! With infrared scanning, our thermal camera can detect abnormalities such as high resistance connections and other hot spots that elude the naked eye. Find out what you have hiding in your panel with an infrared scan from Harrison Electric. Analysis includes infrared and pictorial reports of defects along with verbal consultation.
Large Motor / Generator On-Site Cleaning and Testing
Removal of oil, grease, and other contaminants from exposed windings on large motor generator sets is essential for satisfactory operation. Accumulated residue often causes low winding resistance levels and higher operating temperatures, which could result in catastrophic failure.
We use a multi-faceted approach which includes a combination of vacuum brushing, solvent cleaning, and dry ice blasting, followed by megger, hi-potential, surge, polarization index, and power factor dissipation testing to clean and determine the integrity of the windings. The revitalized windings are then coated with insulating varnish to seal against the elements. Life expectancy is greatly increased.
Correct installation of a motor requires that it be aligned properly with the driven load. Misalignment can result in high vibration, bearing problems, excessive coupling wear, or even a broken shaft. Laser alignment is the solution. Our technicians use state-of-the-art equipment to line up multiple components simultaneously. Smooth, energy-saving operation is the result.
Spare MotorsWhen a spare motor is purchased for important applications, a critical repair can be carried out during a controlled shutdown rather than after a failure causing unpredictable downtime and expense. We can locate some of the hardest-to-find new or used spare motors. We also have some used motors for sale on our site.
