Oil Storage Tanks
A power transformer, basically a square sealed tank, filled with oil approximately 98% full, approx 4000 ltrs of oil. The remaining tank space is vacuum approx -2 or -3 psig. The claim is that when the transformer tank is under slight vacuum, and we attempt to take an oil sample from a port located at the bottom of the tank (approx 3 inches from the bottom) then air is drawn into the tank introducing free air into the system and contaminating the tank environment. To me this is impossible, since the amount of vacuum would have to overcome the wieght of oil above the sample port. Since the tank is approximately 8 ft high, the weight of the oil has to be much greater than 3 pounds per square inch. Can you explain how this can occur? I my many years of experience it takes a very significant vacuum to even slow the flow of oil from a port at the bottom of the tank.+7 Other Responses
