Prospects of nanomaterials use in current and voltage hall sensors to improve the measurements accuracy and reduce the external impacts

This paper provides recommendations on use of the state-of-the-art Hall sensors built on nanotechnology in electrical energy metering. Contemporary power systems (smart grids) use intelligent digital electric energy smart meters built on microprocessor circuits. Such devices are of high accuracy class (up to 0.2S and 0.5S) and except quantitative indicators can measure and analyze the quality parameters of electricity. The external factors, such as ionizing radiation, magnetic field, temperature, affect the meters' work. The use of modern Hall sensors, created using nanotechnology, allows to minimize these negative effects and improve measurement accuracy.
