Wet and humid weather can cause moisture in motor windings. If the windings are cracked from age, the result could be motor winding failure. For motors less than 125-Horsepower, it is usually more cost-effective to replace rather than re-wind the motor. Have your pump or motor contractor do the math to calculate payback on a new high efficiency motor versus the old inefficient one.
Now is the time to pull out those hydraulic tests and compare them to the pump performance curve. If the overall plant efficiency is less than 65%, contact your pump contractor and ask them to assist in determining why the efficiency is low, and explain if there are problems with the pump, well or booster system. If you haven’t had a hydraulic test completed within the past 2-years, please contact your electrical provider or tester to update your test.
If you are not sure who to contact, give us a call and GPC can direct you to the correct testing group, and if needed assist with interpretation of the data.
