Dec 16,2013·Calculation of secondary containment capacity,based on a design criterion of 110% of tank storage capacity Containment surface area = 45 ft x 20 ft = 900 ft.2.Tank volume,based on 100% of tank capacity = 20,000 gallons Tank volume,in cubic feet = 20,000 gallons / 7.48 gallons/ft. How many ppm does a 138 kV transformer have?How many ppm does a 138 kV transformer have?In both figures,where the current IEEE Guide C57.106 [3] has a 25 PPM limit for a 138 kV class transformer,readings varied from 15 to 50 ppm in Figure 1 and 10 to 60 ppm in Figure 2,solely based on the oil temperature.The same charts show that the % Saturation was elevated independent of temperature.Moisture in Transformer Insulation How much water is in a paper transformer?How much water is in a paper transformer?An interesting way to show this involves considering a 1,000-gallon transformer with an estimated 1,100 or so pounds of porous/paper insulation.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.Moisture in Transformer Insulation
