About Photovoltaic Energy StorageThis would mean a perfectly dry transformer would have 780 ppm of moisture in the oil! But we can see how it is the reverse, as depending upon the temperature, often under 10 ppm, but, no more than 10 to 25 ppm of water is the typical expected water content in a dry transformer. What about a transformer starting to show signs of moisture issues?
