Oil moisture meter TOR-1

portable

TOR-1 transformer oil tester is designed to detect the mass fraction of dissolved water in insulating mineral oils the viscosity of which does not exceed 70 cSt at the temperature of 50°C. When operating this device, it is necessary to take into consideration that the tester is only a reference point for fast detection of moisture content; a final analysis requires contacting a certified laboratory. In the best-case scenario, standard laboratory analyses take a day and require a great input of human and financial resources. The use of TOR-1 allows diagnosing the transformer oil as soon as possible and making a quick decision in the field near the transformer. Components of TOR-1 instrument The device combines all the devices necessary for simple and convenient operation: LCD-panel to display the moisture content of tested oil; intake container for tested oil; moisture sensor to detect the mass fraction of moisture in lubricating and insulating oils; printer for paper output of test results. Principle of operation The measurement of moisture in oil is similar to that of moisture in air. The water content in oil can be described as an absolute value in ppm or a relative value of aw: ppm means the ratio between the weight of water and the weight of oil; aw means the actual moisture content as a percentage of the oil fully saturated with moisture. The value aw = 0 stands for moisture-free oil, while aw = 1 stands for the oil fully saturated with moisture.
