Electronic Optical Current And Voltage Transformers

Future of "DIGITAL SUBSTATION" - Electronic Optical Current and Voltage Transformers Complete solutions for digital substations based on fiber-optic instrument sensors.

Advantages:

Less Cost Of Installation And Commissioning:

  • Tightness of optical transformers allows
  • To reduce dimensions of foundations and steel reinforcement capacity
  • To install the equipment in places with the increased seismic activity
  • To reduce costs for transportation and handling operations
  • High fire and explosion safety
  • No high potentials at secondary circuits – better safety for any works on secondary equipment
  • Expenses reduction for Substation maintenance, less frequent power supply interruption for the consumers

High Speed and Accurate Measurement:

  • Expenses reduction for Substation maintenance, less frequent power supply interruption for the consumers
  • Complete galvanic isolation, correspondence to modern Electromagnetic Compatibility requirements
  • Digital signal processing and modern interfaces (correspondence to IEC61850)
  • Highest accuracy of the time-current curve, even in case of aperiodic component availability due to the absence of saturation
  • Wide dynamic range
  • Highest speed of measuring signal conversion

Less Cost For Maintenance:

  • Absence of oil and sulfur hexafluoride in the optical transformers allows
  • To exclude tests for dielectric loss determination and samples examination
  • To exclude monitoring of hexafluoride leakage and oil level control
  • Absence of limitations for recycling

Safety:

  • High fire and explosion safety
  • High seismic safety (9 points by MSK-64 scale)
  • Optical methods of current and voltage parameters measuring
  • Safety of service procedures
