Optical Current Transformer (OCT), also known as magneto-optical optical current transformer, is a large category of electronic current transformers. Its working principle is mainly to use the Faraday magneto-optical effect to measure current based on the principle of Faraday magneto-optical effect. The magnetic field around the measured current is linearly integrated, and the change of polarization angle is converted into the change of output light by using the analyzer. Then, after a series of signal processing, it can not only detect the size of the changing current, but also make accurate measurements of the steady current. The optical current transformer is similar in appearance to the traditional transformer, but is small in size and light in weight. It mainly consists of three parts: sensor head, insulating support and optical cable.

The continuous progress of science and technology has provided technical support for optical current transformers. Due to the various advantages of optical current transformers over traditional transformers, optical current transformers have attracted the attention of the market and their technical level has been continuously broken through.

Due to the small size and simple insulation structure of optical current transformers; no iron core, no magnetic saturation and ferromagnetic resonance; good anti-electromagnetic interference, etc., they are widely used in substations, converter stations, DC power grids, smart grids and other fields. Therefore, domestic and foreign universities, scientific research institutions, and manufacturers continue to increase their investment in scientific research and continuously develop and manufacture photoelectric current transformers of various voltage levels.

With the rapid development of substations, converter stations, DC power grids, and smart grids, the optical current transformer industry has also ushered in a huge development opportunity. The advancement of informatization and intelligence will bring a huge market for the optical current transformer industry. The development of power systems, smart grids, large current measurement, electroplating metallurgy, electromagnetic weapon systems and other fields will bring broad application space for the optical current transformer industry.

In recent years, the country has successively introduced a series of policy measures to support high-end transformers in the power industry, which has greatly improved the matching and allocation of relevant resources, created a good policy and market environment for the development of the transformer industry, and optical current transformers have also ushered in an important development window.
