Transformer Oil Moisture Remover

GlobeCore monitoring technique is based on using the relative humidity of insulating oil. TOR-5 measures the following parameters by means of sensors, 24/7:
temperature of transformer top and bottom oil; active water in transformer top and bottom oil; relative humidity of transformer top and bottom oil; ambient air temperature; relative humidity of ambient air. A high-precision hydrogen sensor is additionally used as an indicator of transformer malfunctions. Hydrogen is formed in oil as one of the first gases already at the temperature of 150 degrees Celsius and accounts for up to 59% of all the gases released during the decomposition of oil molecules. Therefore, the content of this gas in insulating oil is a rather informative parameter for diagnostic evaluation of possible transformer malfunctions, in particular, occurring partial discharges. With partial discharges in oil, the weakest hydrocarbon bonds are broken through ionization with accumulation of hydrogen.
