Split Core Current Transformer: 630–2500A Primary, 0.333V Output
High-capacity split core current transformer designed for 630A–2500A conductors with safe 0.333V voltage output. Ideal for modern digital energy meters, data loggers, and IoT monitoring systems in large industrial and infrastructure applications.
This Split Core Current Transformer is engineered for accurate measurement of high-current AC loads in heavy industrial and commercial environments.
Designed for 630A to 2500A primary conductors, the unit provides a low-level 0.333V secondary voltage output, making it ideal for direct connection to:
-
Digital energy meters
-
Power analysers
-
Data loggers
-
Remote telemetry units (RTUs)
-
IoT energy monitoring gateways
-
Building Management Systems (BMS)
Unlike traditional 5A secondary CTs, the 0.333V output enhances safety and simplifies installation by eliminating high secondary currents. This makes it particularly suitable for modern electronic metering systems.
The split-core design allows non-intrusive installation around existing conductors without disconnecting cabling, reducing downtime in live facilities.
Operating at 50–60Hz, the transformer maintains a phase angle error of less than 2° at 50% rated current, supporting accurate demand monitoring and load profiling.
Typical applications include:
-
Main switchboard incomers
-
Large industrial feeders
-
Generator and transformer monitoring
-
Mining and processing facilities
-
Commercial infrastructure and utilities
-
Solar and renewable energy monitoring
