Maintenance Partners offers a full maintenance solution for oil filled and dry transformers. We offer services for distribution and power transformers of all brands, including: ACEC BBC Helmke Siemens AEG Brush Holec Smit Alstom France Transfo I.E.O. Stromberg ASEA G.E.C. Pauwels / CG Trafo Union Assessment & Maintenance Plan Transformers are low maintenance, but not free of maintenance. To determine the maintenance need of your transformer(s), Maintenance Partners offers an assessment that consists of visual inspections, oil sampling, thermography and electrical measurements. The assessment is the foundation for a maintenance plan in which the condition and priority of each transformer are decisive for the maintenance frequency and needs. Preventive Maintenance For a safe and reliable operation of transformers, preventive maintenance is a must. This detects problems at an early stage and can prevent further deterioration. Preventive maintenance includes the following tests: Oil.

Our field service teams carry out a wide variety of tests and measurements : Vibration analysis Laser alignment Dynamic balancing Oil analysis Electrical analysis Transformer analysis Thermography / Infrared Non-destructive tests (NDT – according to API RP 585, API RP 7G, ASNT SNT-TC-1A & ESC practices) Vibration Analysis Vibrations in a machine are generated by certain elements moving relatively to each other. These vibrations contain a lot of information about the condition of the machine and indicate whether there are problems or not. By performing a vibration analysis we can not only measure the severity of a particular problem, but in many cases, the exact location and cause of the problem. Vibration analysis can detect the following malfunctions: Imbalance Alignment error Eccentricity Bearing condition Condition of Gear Sets Belt and Pulley condition Mechanical looseness Electromagnetically induced forces
