Control transformer - Import export

TOR-1 is a device for quick and precise measurement of the moisture content in insulating oil, even in miniscule quantities. The high sensitivity and excellent long-term stability make this tester an ideal solution for constant control of moisture content in transformer oil. Operating principle The amount of water in the oil can be described as an absolute value in ppm or a relative value of aw: ppm is the ratio of moisture weight to oil weight; aw is the actual water content as a percentage of water content in fully saturated oil. A value of aw = 0 corresponds to completely dry oil, while aw = 1 corresponds to a completely saturated oil. The measurement with this sensor is based on exceptional long-term stability and resistance of capacitance sensor elements to contamination. The measured physical properties are water activity w and temperature T. Using these parameters, the device calculates the amount of water (ppm) in mineral transformer oil.
