Abstract: Molecular sieve material is placed in the main condensate return in vaporization-cooled transformers. The sieve material can be removed and replenished without de-energizing the transformer.

Abstract: The quantity of SF.sub.6 gas dissolved in a halogenated dielectric coolant used in transformers can be determined by heating a sample quantity of the sample gas coolant to the point of cavitation and comparing the temperature and pressure at which cavitation first appears to a graphic representation of the relationship between concentration, pressure and temperature to obtain the gas concentration from the observed temperature point.

Abstract: A cylinder containing a vacuum lid opening at one end and a tee connector is used as a containment vessel to measure the rate of volatilization of dissolved volatiles from solids. One end of the tee is connected to a vacuum pump and the other end is attached to a vacuum pressure gauge. A thermal sensor is located at the bottom end of the cylinder for monitoring the temperature of the solid material. In operation, a sample of contaminated solid is placed in the cylinder, the vacuum pump is activated and the vacuum pressure and solid temperature are monitored over a period of time. The mass transport coefficient for volatilization of dissolved gases from contaminated solids can be determined from Henry's law and a mass transport equation.

Abstract: Immiscibility between polychlorinated biphenyl (PCB) substances and retrofilled non PCB transformer dielectrics allows for the mechanical separation of the PCB substances from the retrofilled dielectrics. Sedimentation, filtration and centrifugation can be employed in the separation process.

Abstract: A pair of calibrated cylinders are connected by means of an interconnecting valve with an inlet valve at one end of one cylinder and a pressure gauge connected to one end of the other cylinder. The first cylinder is filled with condensable coolant containing a noncondensable gas contaminant and is valved off to the atmosphere. When the interconnecting valve between the cylinders is opened the condensable coolant and noncondensable gas are allowed to volatilize into the other cylinder until thermal equilibrium is established between both cylinders. The absolute pressure, which is equal to the sum of the partial pressure of the noncondensable gas and the known vapor pressure of the coolant at the equilibrium temperature, allows the quantity of noncondensable gas to be determined using Henry's Law.
