The most reliable way to determine the water content in transformers is by determining the relative moisture. In that case both media have the same water content. The known characteristic conversion curves are used to determine the water content of the cellulose in vol. %. To that end the device is attached either to the "top" and "bottom" oil probes or to the "top" or "bottom" probe.
The "top" and "bottom" temperatures are then measured via the sensors. This measuring process must be continued for an adequate length of time (i.e. at least 30 min) to ensure that the transformer is not in a dynamic condition of change.. The rugged mechanic system allows also long term measurements. Other measurement systems can be integrated in order to have a temporary monitoring device.
