Moisture in Transformer Fluid
Moisture in Transformer Fluid
(OP)
We have just finished sampling R-Temp fluid filled substation style transformers. The transformers are from various manufacturers and range from 10-15 years old. Eight of the samples all moisture in them.
Does any one know if this is typical of R-Temp fluid from that time period? Any suggestions as to prevent this from happening again?

The fluid is hygroscopic like the mineral transformer oil and requires protection against absorption from atmosphere just like the mineral counter part.
The difference lies in that the moisture coupled with oxygen in air cause rapid deterioration in the properties of the mineral oil whereas the same is not so much of a concern in case of R-Temp (though the moisture will cause reduction in the BDV and is important).
