Types of interaction in the working chamber of AVS 1. Mechanical intensive dispersion of particle components with mixing of ferromagnetic particles due to the chaotic collision. 2. Destructive flows as a result of the action of the electromagnetic lens of the inductor. 3. Hydrodynamic action - expressed in high shear stresses pressure and changes in flow rate. 4. Hydroacoustic in liquid fluid. 5. Micro arcs and electromagnetic field 6. Electrolysis and ionization of water with the release of hydrogen and OH hydroxyl groups, as well as thermal effects. The devices can be effectively used in such industries as: construction - for grinding and mixing building mixtures, activating the surface layer of materials; chemical - for obtaining solutions, melts, emulsions and suspensions; agricultural - for mixing and receiving fertilizers; mining - for processing ore or sludge; machine-building - for obtaining lubricants; food - for juices, pectins, or pastes.

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.

The TOR-2 transformer oil express-tester is designed to determine the moisture and hydrogen content in mineral insulating oils and ether based insulating oils. Moisture and hydrogen content is measured in parts per million (ppm). Knowing the content of hydrogen and moisture in the oil, as well as the rate of parameter change, it is possible to detect problems developing in the transformer in advance and to take timely measures to prevent damage to the transformer. Moisture measurement The device measures the activity of the water using a capacitance sensor, which ensures stability over time and contamination resistance. The oil temperature is also measured. The moisture content is calculated from these measurements. Hydrogen measurement A highly selective solid state sensor immersed directly in oil is used to measure hydrogen content. The sensor ensures accuracy and reliability of direct measurements.

The unit is designed for determining dielectric loss tangent and permittivity of transformer oils and other dielectric fluids according to the IEC 60247. It is a fully automatic device that allows testing according to the procedures defined in these standards, as well as according to the user procedures specified in the appropriate section of the setup menu. Operating principle Measuring the difference in amplitudes and phases of signals obtained when a test sinusoidal voltage with an effective value of up to 2 kV is applied simultaneously to the reference capacitor and the object of measurement, which is the measuring cell of the unit. The difference between the amplitudes of the signals taken from the reference capacitor and the internal electrode of the measuring cell is proportional to the dielectric constant of the liquid under study.
