A split-core current transformer operates on the same fundamental principle as a standard current transformer: electromagnetic induction. It measures alternating current (AC) by inducing a proportional, smaller current in its secondary winding from the magnetic field created by the primary conductor. The defining feature is its hinged or separable iron core, which can be easily opened and clamped around an existing live conductor without the need to disconnect it.
Product Features
1. Easy Installation: The split-core design is its greatest advantage. It allows for quick and safe installation or removal around energized cables, eliminating downtime for wiring modifications.
2. Non-Intrusive Operation: Since it doesn't require breaking the conductor, it is ideal for temporary monitoring, retrofitting into existing electrical panels, and permanent installations where system shutdown is impractical.
3. Convenience and Safety: It provides a safe method for measuring current in already-energized circuits, protecting personnel and preventing disruption to critical processes.
Common Applications
Split-core current transformer are predominantly used for monitoring and measurement where easy access is essential. Their primary applications include:
1. Energy Sub-metering: Monitoring power consumption in specific sections of a building, data center, or industrial plant.
2. Power Monitoring Systems: Integrating with meters and sensors for real-time load analysis, power quality checks, and energy management.
3. Retrofitting and Audits: They are the perfect tool for adding measurement capabilities to existing electrical systems without interrupting power.
