OPTICAL CURRENT TRANSFORMERS
• They offer an excellent class of precision over a wide (virtually unlimited) range.
• Greater safety (without risk of failure due to explosion).
• Environmental protection (without SF6 or insulating gases).
• They are totally passive (do not require secondary power).
• The only active element in the system is the IEC 61850 Merging Unit.

Description
Arteche’s optical current transformers are based on the Faraday effect, measuring the changes that occur in the polarization angle of light when it passes through a magnetic field.
