Bar Type Current Transformer Market is rising with growing demand for smart transformers, digital monitoring, and renewable energy adoption during 2026-2030F.

According to the TechSci Research report, “Bar Type Current Transformer Market – Global Industry Size, Share, Trends, Competition Forecast & Opportunities, 2020-2030F”, the Global Bar Type Current Transformer Market was valued at USD 679.17 Million in 2024 and is projected to reach USD 1,076.63 Million by 2030, growing at a CAGR of 7.82% during the forecast period.

This growth is largely attributed to the increasing integration of digital and smart technologies into current transformers, the expansion of renewable energy infrastructure, and ongoing investments in transmission and distribution networks worldwide.

Digitalization and the Rise of Smart Current Transformers

One of the most transformative trends shaping the bar type current transformer (CT) market is the shift toward digitalization. Traditional CTs, once limited to basic current measurement, are increasingly being replaced or supplemented by digital CTs that integrate:

• Communication interfaces for real-time data exchange

• Signal converters for accurate transmission of electrical parameters

• Remote monitoring and diagnostic capabilities

These smart CTs deliver higher accuracy, faster response times, and seamless integration with intelligent electronic devices (IEDs), supervisory control and data acquisition (SCADA) systems, and advanced metering infrastructure (AMI).

The move toward digital substations in developed economies is accelerating adoption. Utilities and industrial operators are seeking solutions that not only measure current but also provide high-fidelity data for:

• Grid analytics

• Predictive maintenance

• Remote diagnostics

Manufacturers are responding by offering bar type CTs equipped with digital signal outputs, embedded microcontrollers, and cloud-compatible data interfaces.

Role of Smart Grids and Industry 4.0

The integration of smart grids and automated energy management systems has amplified demand for digital CTs. Governments and regulatory bodies worldwide are mandating the development of intelligent grids to improve resilience, efficiency, and sustainability.

While digital CTs come with higher upfront costs compared to conventional models, their long-term benefits—such as improved fault detection, asset monitoring, and operational efficiency—make them an increasingly viable choice.

Moreover, this digitalization trend aligns with the global movement toward Industry 4.0, where real-time electrical data plays a critical role in machine learning algorithms, industrial automation, and energy optimization models. Consequently, both product development strategies of manufacturers and procurement policies of utilities are being reshaped around smart CT technologies.

Market Segmentation by Type

Outdoor Bar Type CTs: The Fastest Growing Segment

By type, outdoor bar type current transformers are emerging as the fastest-growing segment during the forecast period. This surge is linked to the increasing demand for reliable current measurement in high-voltage, outdoor environments, particularly in:

• Transmission and distribution (T&D) infrastructure projects

• Renewable energy installations like wind and solar farms

• Rural electrification programs in developing regions

Outdoor CTs are designed to withstand harsh conditions such as temperature extremes, UV radiation, dust, and moisture. Their robust construction—often oil-immersed or resin-insulated—provides enhanced insulation, superior thermal performance, and extended service life.

These CTs are particularly crucial for:

• Pole-mounted transformers

• Outdoor substations

• Switchyards in renewable energy projects

As global investments in renewable energy continue, especially in remote areas, outdoor CTs are expected to play an increasingly pivotal role.

Technological Advancements Enhancing Outdoor CT Reliability

Recent innovations have strengthened the case for outdoor bar type CTs, including:

• Weatherproof enclosures for enhanced durability

• Anti-corrosion coatings to extend life in harsh climates

• Improved sealing techniques to prevent moisture ingress

Additionally, the integration of digital monitoring features into outdoor CTs ensures not only robustness but also data-driven intelligence for grid operators. These developments collectively support the segment’s robust growth outlook.
