    Selecting, sizing transformers for commercial buildings

    Jun 09, 2011 · Transformers change voltage levels to supply electrical loads with the voltages they require. They supply the required incoming electrical service to the buildings. Transformer primary and secondary voltages can be 2,400; 4,160; 7,200; 12,470; and 13,200 for 15-kV Class, and 120, 208, 240, 277, and 480 for 600-V Class.Transformer conservator tanks | T&D Guardian Articles french transformer tank building volumeThe transformer conservator tank acts similarly to the overflow tank on the radiator of a car. As the transformer load cycles, so does the oil temperature. All fluids, including transformer oil, change volume when the temperature changes. Common transformer oil changes volume Knowing Liquid-Filled Transformer Installation Requirements* If the nominal voltage is 600V or less, the vault may be omitted if arrangements are made to prevent a transformer oil fire from igniting other materials, and the total transformer capacity does not exceed 10kVA in a section of a building classified as combustible or 75kVA in a section of a building classified as fire-resistant construction.

    DESIGN OF TRANSFORMER

    In core type transformer the ratio of depth to width of core varies between 1.4 to 2. In shell type transformer width of central limb is 2 to 3 times the depth of core. Square and stepped cores:For high voltage transformers, where circular coils are required, square and stepped cores are used. 11.Transformers: Basics, Maintenance, and DiagnosticsFrom the solubility table (table 12) below, comparing hydrogen with a solubility of 7% and acetylene with a solubility of 400%, you can see that transformer oil has a much greater capacity for dissolving acetylene. However, 7% hydrogen by volume represents 70,000 ppm, and 400% acetylene represents 4,000,000 ppm.Safety Clearance Recommendations for TransformerDistance (min) Over 35KV.

    Where a firewall is provided between transformers, it should extend at least 1 ft (0.31 m) above the top of the transformer casing and oil conservator tank and at least 2 ft (0.61 m) beyond the width of the transformer and cooling radiators or to the edge of the containment area, whichever is greater. Power transformer fire protection systemsBuild Your Own Spring Reverb | Tape Op Magazine | Tanks with low Zin (8-16 ohms) need a lot of current, whereas tanks with a high Zin (1-3 kohms) need high voltage rails (i.e., tube amps). Ive found that tanks with intermediate Zin (50-300 ohms) were a good choice for typical +-15<->24 VDC rails, where a reasonable amount of power can be delivered without either high current or high voltage french transformer tank building volume
