According to Stratistics MRC, the Global Optical Current Transformer Market is accounted for $43.54 million in 2025 and is expected to reach $85.94 million by 2032 growing at a CAGR of 10.2% during the forecast period. An Optical Current Transformer (OCT) is an advanced electrical measurement device that uses optical fibers to measure and monitor current flow in electrical systems. Unlike traditional current transformers, OCTs offer immunity to electromagnetic interference (EMI) and provide accurate, real-time current measurements over long distances. OCTs utilize the principles of the Faraday Effect or magneto-optic effect to convert current measurements into optical signals. They are widely used in power transmission, smart grids, renewable energy systems, and industrial applications for reliable and precise monitoring.
