U.S. Current Transformer Market (2025 - 2030) Size, Share & Trends Analysis Report By Voltage (Low Voltage, Medium Voltage, High Voltage), By Application (Power Distribution, Manufacturing), And Segment Forecasts

U.S. Current Transformer Market Summary

The U.S. current transformer market size was valued at USD 534.0 million in 2024 and is projected to reach USD 680.6 million by 2030, growing at a CAGR of 4.2% from 2025 to 2030. The industry is expected to grow due to rising demand for efficient energy monitoring and control across the industrial, utility, and commercial sectors.

The current transformer industry in the U.S. is primarily driven by the increasing demand for electricity due to rapid urbanization, industrialization, and the ongoing modernization of aging power infrastructure.  In alignment with this growing need, in March 2024, the U.S. Department of Energy announced a USD 18 million funding opportunity under the Flexible Innovative Transformer Technologies (FITT) program. Technological advancements are profoundly reshaping the U.S. current transformer market, with a notable shift towards smart digital transformers that offer advanced real-time monitoring, predictive maintenance, and automated energy optimization, leading to reductions in downtime.

Innovations include integrating IoT-enabled sensors and digital signal processing for enhanced accuracy and reliability, especially for smart grid deployments. Manufacturers also focus on miniaturization and lightweight designs to facilitate easier installation and improve performance in space-constrained areas, particularly for industrial automation and building energy management systems.

Key players often engage in strategic acquisitions to expand their product portfolios, gain access to new technologies, enhance market share, and consolidate their presence in specific regions or end-use segments. In October 2024, Standex International Corporation acquired U.S.-based Amran Instrument Transformers and Narayan Powertech Pvt. Ltd. (India-based). This is expected to expand presence in the high-margin, fast-growing electrical grid end market, and benefit from capacity expansion, infrastructure upgrades, and data center demand.

Voltage Insights

The medium voltage segment dominated the industry with a 50.3% revenue share in 2024. This dominance is primarily attributed to their essential role in monitoring and protecting power systems, which form the backbone of power distribution networks, industrial facilities, and commercial buildings across the nation. Medium voltage current transformers are crucial for ensuring electrical safety, enabling accurate fault detection, and enhancing system efficiency in these critical infrastructure areas.

The low voltage segment is projected to grow at the fastest CAGR from 2025 to 2030. This accelerated growth is driven by the increasing need for precise and reliable current measurements in diverse low-voltage applications, including industrial automation, residential and commercial building energy management systems, and the burgeoning electric vehicle (EV) charging infrastructure. The rising demand for energy-efficient solutions across various industrial sectors, continuous technological innovations, and a shift towards optimized electrical systems are fueling this expansion.

Application Insights

The power distribution segment dominated the market with the highest revenue share in 2024, driven by the ongoing modernization of the electrical grid and increasing demand for a reliable energy supply. Utilities and power companies actively deploy current transformers in substations and transmission networks to enhance monitoring, protection, and control functions.

The manufacturing segment is projected to grow significantly from 2025 to 2030. The increasing reliance of manufacturing facilities on advanced electrical systems for process automation, energy management, and equipment protection primarily fuels this accelerated growth. Current transformers are essential in manufacturing applications such as load monitoring, power quality analysis, and safeguarding machinery from overloads or faults, all contributing to enhanced operational efficiency and safety.
