Transformers can draw air into the tanks through breathing action that results from changes in the volume of liquid, and air in the tank that occurs with changes in temperature. Most modern transformer constructions are tightly sealed and do not breathe if they are free from leaks.HOW DO I CALCULATE THE VOLUME OF MY Step 4: Compare the answers in Step 1 and Step 3 to determine if the dike will hold 110% of the volume of the tank. The answer in Step 3 must be equal to or greater than the answer in Step 1. over . 9/01 SITUATION 2: More than one tank within the diked areaSelecting, sizing transformers for commercial buildingsJun 09, 2011 · Transformer size in kVA = 42 kVA x 1.25 = 52.5 kVA. Therefore, a 75 kVA transformer would be selected for this application out of the available standard ratings for a 480 V primary to 208 Y/120 V secondary. The most common building industry standard ratings are 3, 6, 9, 15, 30, 37.5, 45, 75, 112.5, 150, 225, 300, 500, 750, and 1,000 kVA.

In an electrical power transformer, there are primary, secondary and sometimes also tertiary windings. The performance of a transformer mainly depends upon the flux linkages between these windings. For efficient flux linking between these windings, one low reluctance magnetic path common to all windings should be provided in the transformer.
Transformer may be designed to make one of the following quantity as minimum i. Total volume ii. Total weight iii. Total cost iv. Total loss All these quantities vary with ratio r = m/ AT. If we choose high value of rthen flux will be high, so large cross section is required which will increase volume, weight and cost of FIST 3-30 TRANSFORMER MAINTENANCEAcronyms and Abbreviations A air ANA self-cooled, nonventilated kW kilowatt ANSI American National Standards IEEE Institute of Electrical and Institute Electronic Engineers CEGB Central Electric Generating M/DW moisture by dry weight Board mg milligram cfm cubic feet per minute mva mega-volt-amps CH 4 methane ND not detected C 2 H 2 acetylene N 2 nitrogenFire Protection in Substation Transformers | T&D WorldWhere 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 systems
In case of large transformers some of the accessories are despatched separately. 5.1.2 Transformer tank is filled with oil or pure dry inert gas depending upon the transport weight limitations. In case the tank is filled with oil, sufficient space is left above the oil to take care of the expansion of the oil.Gas insulated power transformers: A growing technology uzbekistan transformer tank building volumeSignificant tank pressure increase does not occur during internal failures due to the gas characteristic, and the risk of a tank explosion or fire incident can be eliminated completely .
