electrical transformers containing oil and/or PCBs Treat interconnected tanks as a single tank of equivalent total volume for the purposes of the bund design criteria.For flammable liquids,bund capacity should be at least 133% of the net capacity of the largest tank. Chemical resistant linings on bunds have been damaged. How much moisture is in oil in a transformer?How much moisture is in oil in a transformer?If one-half percent of this weight is moisture,and if completely in the oil,it would be just over 5 pounds of water dissolved in 1,000 gallons (7,500 pounds) of oil.This would mean a perfectly dry transformer would have 780 ppm of moisture in the oil!Moisture in Transformer Insulation How much oil is in a conservator transformer?How much oil is in a conservator transformer?Typically,when the conservator is filled to the 25°C mark,the tank is approximately 25-35% full.This leaves enough room for oil expansion when the transformer is operating at full load and the average oil temperature is in the range of 70-90°C.Transformer conservator tanks TD Guardian Articles
A new definition of storage tank was added in 1993 that established 60 gallons capacity as the minimum quantity for a vessel to be considered a storage tank.This,in effect,sets a lower limit to the applicability of Chapter 21,and subsequent tankrelated chapters of NFPA 30.4.40 CFR § 264.193 - Containment and detection of releases (d) Secondary containment for tanks must include one or more of the following devices (1) A liner (external to the tank); (2) A vault; (3) A double-walled tank; or (4) An equivalent device as approved by the Regional Administrator.(e) In addition to the requirements of paragraphs (b),(c),and (d) of this section,secondary containment systems must satisfy the following requirements:
