Production of nano-enabled fiber optic systems for measuring current and voltage in power grids

Profotech will produce fiber-optic systems for measuring energy use and power grid protection. By incorporating nanofibers into its fiber optic current and voltage sensors, Profotech is able to provide innovative solutions to the power industry and other energy-intensive industrial sectors and to replace imports with domestic products that have better consumer properties. The nanofibers owe their superior technical characteristics to nanosized quartz ribs, 50 nanometers to 80 nanometers, inside the load-bearing quartz sheath on which the fiber’s core is hung.

Fiber optic sensors pave the way for intelligent energy systems like SmartGrid, ensuring the exactitude of measurement required in such networks. The sensors also make it possible to control and manage electric power grids in real time.

Areas of application

  • Power industry
  • SmartGrids and other intelligent energy systems
  • Transportation
  • Metallurgy
  • Mining


  • Energy producers and related companies and businesses with intensive energy use

Competitive advantages

  • Virtually service free
  • Particularly sensitive measurement
  • Impervious to external activities
  • Safe from fire and explosion
  • Reduces unaccounted energy use by 90%
  • Eliminates service disruptions

Optical nanofiber can achieve specific measurement sensitivities and resistance in harsh environments. Technical characteristics are obtained due to the presence of 50-nanometer to 80-nanometer quartz elements in the fiber.
