green transformation of energy structures and the continuous application of intelligent power facility technologies , the application of the IOT in power systems, industrial automation systems , smart buildings , and green new energy is expanding.
As a key component in power monitoring and energy efficiency management, current transformers (CTs) serve as a bridge between physical analog power signals and digital signals in IoT systems .
In particular , Heyi Electric’s KCT series current transformer split core, with their high precision, easy installation, and multi-scenario applicability, have become a crucial component of smart power monitoring in the IoT era .

Easy installation, non-invasive design
KCT uses a split-core design that allows it to be directly mounted on existing conductors or busbars without disconnecting the power supply . This design is particularly suitable for rapid retrofit scenarios and limited installation space.
Excellent security and stability
KCT has built-in precision resistors to ensure low voltage safety output.
The insulated PC shell is UL94-V0 certified and has excellent flame retardant and isolation properties.
A variety of models are available to cover a wide current range of 5A-1000A, thus meeting various needs from civil to industrial use.
HEYI’s KCT products maintain stable accuracy (error ≤ ±1.0%) within the frequency range of 50Hz–2kHz, enabling monitoring of power quality, harmonics, and transient events.
Sub-metering:
KCT split-type current transformers can accurately record energy consumption data of different circuits and equipment, providing a foundation for distributed and precise energy management of smart grids .
Load monitoring and three-phase circuit balancing:
By collecting KCT current transformer data through the IoT platform, power companies can accurately monitor the grid’s operating status in real time, optimize power distribution plans , improve efficiency, and reduce line losses.

Motor and compressor monitoring :
In industrial sites, KCT can monitor and collect real-time operating currents of equipment such as motors and air compressors.
Combined with IoT data analysis, it can provide early warnings of abnormal power consumption and current overloads, thereby extending the life of motors and compressors .
PLC power measurement device:
By connecting with PLC and SCADA systems, KCT current transformer split core enable visual management of workshop power consumption, helping companies reduce power consumption .
Data centers and buildings :
In smart buildings , KCT can be integrated into power consumption monitoring platforms for zoned power consumption analysis, peak and valley electricity price optimization, and power load management.
Power safety warning:
Abnormal current data is transmitted to the power monitoring system through the IOT, which can quickly locate potential short circuit or overload risks and improve building operation safety.

Photovoltaic and wind power generation:
In the inverter system, KCT can monitor the current on the power generation side and the grid-connected side in real time, helping new energy power stations achieve remote power monitoring and equipment maintenance .
Microgrid applications:
With the support of the IoT platform, KCT current transformer can help build distributed power systems and achieve coordinated scheduling and optimization of multiple energy sources.
By connecting to the IoT platform, the KCT series current transformer not only provides current data collection and monitoring functions, but also effectively supports application scenarios such as big data analysis, artificial intelligence diagnosis, and remote control.
With the development of 5G technology and edge computing, its application prospects may include the following aspects :
smart home circuits :
Combined with smart sockets and power consumption monitoring platforms, it can realize sub-item monitoring of household electricity consumption and automatically confirm energy-saving solutions .
Smart management of urban energy :
In the urban energy IoT platform, KCT current transformers can serve as a basic data source to promote the green upgrade of urban energy structure .
Carbon neutrality and green development:
Through precise monitoring and data analysis, it is conducive to achieving carbon emission tracking and energy conservation and emission reduction goals.
Empowered by the IOT, KCT split-core current transformer are essential current acquisition components and key nodes in smart energy management systems.
Their high precision, convenience , and diverse applications serve a wide range of applications, including smart grids, industrial automation, building energy management, and new energy systems.
As IoT technology matures, KCT series current transformers will play an even more crucial role in smart energy and the green, low-carbon transition.
