Industry Overview

Non-intrusive current transformers market was valued at $2.7 billion in 2024 and is projected to reach $4.80 billion by 2035, growing at a CAGR of 5.4% during the forecast period (2025–2035). Non-intrusive current transformers are advanced monitoring devices that measure electrical current without requiring direct contact with or disconnection of conductors. These CTs, often designed as split-core or clamp-on systems, provide safe, efficient, and cost-effective solutions for current measurement.

Global non-intrusive current transformers (NICT) market is increasingly dominated by the rising demand for accurate and reliable energy monitoring systems driven by the growth of electric vehicles, renewable integration, and smart grid development. These transformers enable safe, non-disruptive measurement of electrical currents, making them critical for modern power systems where uninterrupted operation and precision are essential.

The shift toward electrification, digitalization of energy infrastructure, and the increasing focus on energy efficiency and sustainability are further accelerating their adoption. Moreover, industries and utilities are investing in advanced monitoring technologies to enhance grid resilience, optimize power consumption, and meet regulatory standards, positioning NICTs as a cornerstone technology in the global transition toward intelligent and sustainable energy systems.

  • In April 2023, LEM unveiled the CAB 1500, a new automotive-grade current sensor designed to deliver highly accurate battery charge level measurement for Li-ion battery management systems. Leveraging fluxgate transducer technology, the sensor ensures reliable coulomb counting, enabling precise state of charge (SoC) estimation—critical for maximizing EV range. Certified to ISO 26262 (ASIL-C) and supporting CAN communication, it offers EV designers a robust, non-intrusive solution for next-generation battery systems.

Market Dynamics

Regulatory Support & Fast-Track Approvals

Supportive regulatory policies and grid modernization initiatives are accelerating the adoption of non-intrusive current transformer solutions globally. Governments and energy regulators are prioritizing advanced metering, real-time monitoring, and safe electrical infrastructure upgrades through incentive programs, compliance mandates, and public–private partnerships. These initiatives reduce deployment hurdles, promote investment in smart grid technologies, and encourage utilities to adopt non-intrusive devices for accurate and safe current measurement. Agencies such as the U.S. Department of Energy (DOE), European Network of Transmission System Operators for Electricity (ENTSO-E), and national power authorities in the Asia-Pacific are introducing guidelines for advanced sensing and monitoring systems.

Growing Demand for Safe and Efficient Monitoring Solutions Driving Market Growth

The increasing focus on electrical safety, operational efficiency, and uninterrupted energy monitoring is shaping the non-intrusive current transformers market. Unlike traditional CTs, non-intrusive devices can be installed without disconnecting live circuits, making them ideal for critical infrastructure, industrial automation, and retrofit projects. Compact and flexible in design, split-core and clamp-on NICTs enable accurate measurement for predictive maintenance, energy optimization, and fault detection in real time.

For instance, in 2023, Schneider Electric introduced its range of split-core current transformers integrated with IoT-enabled power monitoring systems, designed for retrofitting in commercial buildings without power shutdowns. These devices allow facility managers to track energy usage patterns, detect anomalies, and improve efficiency without operational disruption, showcasing how non-intrusive solutions are meeting the demand for safer and more efficient electrical monitoring.

Market Segmentation

  • Based on the application, the market is segmented into electricity, industrial, transportation, electronic, and other.
  • Based on the types, the market is segmented into split core and solid core.

Electricity Sector Leads the Market with Safety and Efficiency Benefits

The electricity sector is projected to remain the largest application segment in the global non-intrusive current transformers market, driven by the growing need for safe, efficient, and real-time monitoring of electrical systems. Non-intrusive current transformers enable contactless current measurement, allowing utilities and industrial facilities to monitor energy usage, detect anomalies, and optimize operations without interrupting the power supply. For instance, ABB provides ANSI indoor current transformers suitable for voltage classes from 0.6 kV to 69 kV. These transformers are integral to medium-voltage applications, offering precise current measurement and protection in substations and industrial facilities.

Split-Core Technology Dominates the Market

Among types, split-core current transformers account for the largest share, with ease of installation, flexibility, and minimal operational disruption. These devices are widely adopted across industrial, transportation, and electronic applications due to their ability to retrofit existing systems without disconnecting conductors. Companies like Siemens and Schneider Electric, and YDRAMEM offer advanced split-core NICTs that combine high accuracy with durability, enabling continuous monitoring, predictive maintenance, and energy optimization. For instance, Siemens provides the SCT-SCM-0200-U model, a split-core current transformer that offers a linear output voltage directly proportional to the input current. This feature ensures accurate current measurement, making it suitable for applications like building automation, tenant submetering, and energy management systems. Moreover, Schneider Electric offers the METSECTSP5A3080U model, a split-core current transformer designed for easy installation without the need to disconnect existing wiring. This device is compatible with Schneider Electric's energy meters, such as the PowerLogic series, facilitating efficient energy monitoring and management in various applications.
