Page 26: Typical Applications
User's Guide ______________________________________________________________________ Typical Applications Method Used for Measuring Moisture in Oil The MMT330 transmitter measures water in oil in terms of water activity (aw) which can be determined as follows: water activity indicates the amount of oil in the scale of 0 - 1 aw. In this scale, 0 aw is an indication of completely water free oil and 1 aw an indication of oil fully saturated with water. -
Page 27: Transformer Oil
Moisture level in oil is thus a true indicator of moisture present in the paper insulation. In addition, it must be noted that capacity of oil to absorb water depends both on the chemical structure of the oil and the additives.
