- Description
- The scope for this project consists of the contractor providing the following services to include but not limited to all things necessary for: furnishing supervision, engineering, labor, materials, and equipment to drain, store, process (as suggested in IEEE C57.106 table 5 class I) and vacuum fill the oil in two main transformers in accordance with the detailed requirements of the attached scope of work document and standard utility practices. The Contractor shall provide all vacuum equipment and any temporary oil storage facilities required for draining, handling and processing the transformer oil. The work to be performed by the contractor includes but is not limited to: 1) Drain the transformer oil out of the transformer tank, while maintaining a positive pressure on the tank using either dry air or nitrogen to prevent the ingress of air and/or moisture; 2) Temporarily store the transformer oil on site. Oil storage locations will be arranged with the Power Project Manager. A certificate of cleanliness shall be provided to the Government for any temporary oil storage tanks. 3) Process the transformer oil including dehydration, degassing, filtering (filter-press method), and adding oil oxidation inhibitor. The oxidation inhibitor shall be type DPBC, premixed in a concentrated transformer oil solution to mix with the approximately 5000 gallons of oil in each of the two transformers to result in a final oxidation inhibitor level of 0.2% to 0.3% by weight. 4) Vacuum-Filling of Transformer Oil. The Contractor is responsible for the provision of all oil handling and high-vacuum processing equipment for filling of the transformer tanks. The contractor shall be responsible for removing any equipment mounted to the transformer tank that is not rated to withstand full vacuum pressures. The contractor shall supply and install necessary provisions to seal openings created by removing such equipment. Transformer manufacturer's specifics and requirements shall be followed. All the valves and blanks shall be checked for leakage at vacuum treatment under 1 mmHg per IEEE C57.93. Each transformer shall be vacuum-filled with hot oil, and the insulation dried using high-vacuum hot-oil recirculation for at least 24 hours. The final oil sample water content shall be less than 35 ppm per the requirements of IEEE C57.93 and C57.106. The temperature of the transformer oil during the filling process shall be between 25 and 90 C, and at least 10 C higher than the dew point. The oil shall be circulated for a minimum of one full pass. Filling, at least to above the core and coils, shall be in one continuous operation. If the vacuum is broken for any substantial period, it may require draining and refilling. Maintain a positive inlet liquid hose gauge pressure during the entire filling process. Transformer oil Tests - After transformer oil filling and processing, samples of the transformer insulating oil shall be taken from the transformer, and sent to two independent laboratories for analysis. Oil samples shall be taken from the transformer per the requirements of ASTM D 923. Identity of samples and results of analyses shall be provided to the Government. Results will be furnished within five days of completing the vacuum filling process. The following analyses shall be performed, as a minimum: a. Dissolved gases, b. Water, c. Neutralization number, d. Interfacial tension e. PCB-in-oil, f. Dissipation factor, g. Dielectric breakdown voltage, h. Furans, i. Dissolved metals, j. Sediment and soluble sludge, k. Oxidation stability, l, Oxidation inhibitor, m. Viscosity, n. Specific gravity, o. Color, p. Flash point and q. Corrosive sulfur. Never open the transformer unless the temperature of the tank and internal parts is as least 10 C higher than the dew point of the outside air. Extreme care must be taken to protect the transformer insulation from damage and to prevent foreign materials from being introduced into the tank. All tools must be accounted for. If possible, tools should have lines made from clean cotton tape or seine cord attached so that they cannot be lost. If any object is dropped into the transformer and cannot be retrieved, a USACE representative must be notified immediately. Note No. 1: United States government is not responsible for providing you with notifications of any changes to this solicitation. The solicitation will be available only as a direct download. This solicitation will not be issued on CD-ROM. Neither telephonic, mailed, nor fax requests will be accepted.
