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.

The unit is designed to measure the dielectric strength of transformer oil and other dielectric fluids according to IEC 60156, ASTM D877, ASTM D1816. It is a fully automatic device - 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. The core of the unit is the high voltage transformer and electronic modules. The unit operates by gradually increasing the voltage on the secondary winding of the high voltage transformer from zero to the maximum voltage, or to the voltage at which an electric breakthrough occurs in the dielectric fluid in the measuring cell installed on the high voltage contacts of the transformer. During operation, AC (50-60Hz) voltage is supplied from the secondary winding terminals through the cell electrodes into the dielectric fluid in the measuring cell.

GlobeCore manufactures oil regeneration systems for both transformer manufacturers and for transformer service providers. GlobeCore units are loaded with a sorbent that captures all oil decomposition products. GlobeCore regeneration systems can use the same sorbent for up to 3 years before the first replacement. No more need for consumables and costly labor related to replacement of exhausted sorbent on the job site. Regeneration systems can be combined with degassing units or can be purchased as stand-alone systems. GlobeCore regeneration systems can be used in combination with your existing degassing or drying unit. Each GlobeCore unit can be customized and includes a number of options: An extra vacuum pump assembly for transformer vacuuming Mounted on a trailer or a semi-trailer Inlet and/or outlet moisture meters for the oil stream Remote control and process monitoring via smartphone or PC Climate Controlled Operator work room.

This GlobeCore mobile oil processing unit is designed for degassing, removal of solids and heating of oil for power transformers with voltage up to 1,150 kV. The unit can be used to: (1) heat electrical systems that contain insulating oil with hot oil; (2) for vacuum drying of transformers and (3) for vacuumizing. The unit is best suited to facilities that install, repair and service oil filled electric power transformers and other oil filled electrical equipment. The unit is not certified for use in and around explosive gases, toxic gases or other aggressive environments. When indoors or other enclosed spaces, exhaust gases must be vented to the outside through hoses or pipelines. no need to use adsorbents to dehydrate transformer oil; operation of equipment causes no air pollution or waste requiring storage and disposal; easy to operate and maintain; maximum oil specifications even after one treatment cycle; low power consumption; low noise level;
