Split Core Current Transformer – 250–1000A Primary / 5A Secondary
Heavy-duty split core current transformer for high-current industrial applications. Designed for 250A–1000A primary conductors with 5A secondary output for energy meters, protection relays, and power monitoring systems.
This high-capacity Split Core Current Transformer (CT) is engineered for accurate measurement of large AC loads in commercial and industrial power systems.
Supporting a primary current range of 250A to 1000A with a standard 5A secondary output, the CT integrates seamlessly with:
-
Three-phase energy meters
-
Power quality analysers
-
SCADA systems
-
Building Management Systems (BMS)
-
Protection and monitoring relays
-
Industrial IoT gateways
The split-core construction enables fast, non-intrusive installation around existing conductors without disconnecting live cabling, making it ideal for retrofit upgrades, load studies, and energy audits.
Designed for 50–60Hz power systems, the unit delivers stable measurement accuracy with a phase angle error of less than 2° at 50% rated current, supporting reliable load analysis and demand monitoring.
Typical applications include:
-
Main incomers and large distribution feeders
-
Industrial switchboards
-
Mining and processing plants
-
Generator and transformer monitoring
-
Solar farm AC output monitoring
-
Heavy manufacturing equipment
