Product Description
Three-Phase Through-Type Current Isolating Transformer—200A Version
High-Accuracy, Wide-Range Current Isolation for Energy Meter Testing
Overview
When testing three-phase energy meters with inseparable voltage and current circuits (closed links), current isolation is essential for accurate measurements. The Three-Phase Through-Type Current Isolating Transformer (ICT) provides true 1:1 current isolation with electronic error compensation, enabling precise, safe calibration under equipotential conditions.
Each ICT contains three independent 1:1 current transformers, designed for:
- Three-phase energy meters with non-separated voltage/current circuits
- Single-phase meters under non-separated conditions
- Multi-station meter test benches requiring equipotential current supply per position
The ICT maintains high accuracy across different meter types and burdens through electronic error compensation and offers substantial secondary output capacity. At 200 A, the secondary delivers over 120 VA while maintaining precision. The system monitors for secondary open-circuit/overload conditions with visual indication and automatic short-circuit protection.
Key Features
- Ultra-wide range: 0.1-200 A primary / 0.1-200 A secondary (1:1 ratio)
- Single-turn through-type structure for minimal loss and maximum efficiency
- High output capacity: up to 140 VA at 200 A
- Electronic error compensation for 0.01% class accuracy across full range
- Secondary open-circuit and overload indication with alarm and automatic protection
- External status indicators and control buttons for operational convenience
- Supports multi-ICT series primary connection with isolated secondary outputs per meter position
Typical Applications
- Three-phase and single-phase energy meter calibration (closed-link meters)
- Multi-position meter test benches using equipotential method
- Utility and metrology labs requiring high-accuracy current isolation

Connection Guidelines
For multi-ICT setups: Connect primaries in series and use each secondary independently to supply the meter under test. Always utilize the provided protection features to prevent secondary open-circuit conditions at high current.
Safety & Protection
- Secondary open-circuit/overload detection with visual indication and alarm
- Automatic secondary short-circuit protection for device safety and stability
- High insulation strength between primary, secondary, and enclosure
