Issues with miscibility of two transformer oils
Issues with miscibility of two transformer oils
(OP)
Hello
We have two types of tranformers from China. One is 150MVA and the other one is 10MVA.
We are not sure of the type of oil used in these transformers.
Are there any miscibility tests that we can do before buying oil from local market?
What precautions need to be taken?
Which standards (IEC) deals with miscibility of oils?
Whom can I contact for furhter help?

If you want to mix more, or to check suitability correctly , prepare oil samples as per the proportion you want to mix and conduct oxidation stability test.Compare this result with individual oil oxidation stabilty test results. It should not be far worse than individual results.

Before placing order for any oil which tests we can run oils in our two transformers to determine which oil we should purchase that is miscible with oils in our transformers and in which proportions?
Does anyone knows about tests that can be performed on oils to determine if an oil is parafenic or napthenic, inhibited or uninhibited and to determine which IEC class it belongs?
Which oil suppliers I should contact for getting further information?
