Oil Processing
Transformer Services Inc. has developed a highly specialized program for oil purification and reconditioning. With our mobile oil processing systems we can provide oil filtration services for transformers of any size throughout a large geographical area. Oil quality is enhanced through:
- Removal of water vapors (free stand or oil dissolved)
- Removal of particulate material
- Acid neutralization
- Degasification: remove dissolved gases such as Ethane, Methane, Hydrogen, Acetylene,Ethylene, Carbon Monoxide and Carbon Dioxide
We use the latest technology and equipment to meet or exceed industry performance standards set by the National Emergency Management Association (NEMA), and the Institute of Electrical and Electronics Engineers (IEEE).
Sampling & Analysis
As transformers age, gaseous and liquid contaminants dissolve in the dielectric fluid and can lead to failures or shorten the life of equipment, unless detected and treated early. Sampling and analysis of dielectric fluid is the key to an effective transformer preventive maintenance program. Sampled transformer oil is analyzed periodically using gas chromatographs, spectrometers, and other specialized testing equipment. Test results show the types and amounts of contaminants and how they have changed from year to year. Contaminants occur as a result of aging, overheating, leaks, or other performance problems.
When the oil samples are collected, a complete visual inspection of the transformer is also performed. Leaks, cracked bushings, inoperative gauges, low oil levels and other defects are identified and noted. Nameplate and other operational data are recorded to help develop maintenance recommendations. A transformer engineer reviews the inspection reports and test results, analyzing prior performance history, usage and age of the transformer. A written report and trend analysis of the sample results, visual inspection, and maintenance recommendations are provided to the customer.
