Electromagnetic transformers are traditionally used in power electric engineering for electric current measuring. But, unfortunately, the high-voltage insulation of classical transformers does not have sufficient reliability at voltages 110–750 kV, and such transformers are prone to creating explosive and fire-dangerous situations. In the first part of the review, the physical principle of the optical method of current measuring based on the Faraday effect were discussed. The second part of the review is devoted to the technical implementation of this method.
