Pressure changes in the gas space of sealed transformers are discussed, and the necessary formulas to compute the equilibrium pressure corresponding to a given load condition are derived. It is shown that when gas solubility effects are included, the

Three different comnercially avaiTable transformer oils were evaluated for their electrostatic charging behavior. One of these oils was found to have a higher charging tendency than the others. The charging behavior of this oil was moisture dependent

A study of particle levels in transformer oil was conducted, covering about 200 samples taken from field and factory units. Factory samples were included to determine a relative base condition on which to compare field data. Particle distribution cur

In recent years much attention has been given to oil flow in power transformers with cellulosic insulation, due to the failure of some field units from discharges resulting from charge accumulation. Charge separation is a function of several factors:

Gas-in-oil analysis on large power transformers during factory tests is discussed. Measurement of levels of combustible gases generated during the usual 24 hour heat run provides valuable information on the condition and performance of the unit. Inci

Electrical equipment such as power transformers with a paper-oil insulating system have varying moisture levels dependent on ambient and operating conditions. The total water content is distributed between the paper and the oil in a ratio that is pre
