Product Description

Heavy-Duty Current Transformer (CT) Series | Solid-Core, Split-Core, Busbar Window & Flexible Rogowski Coil | High-Precision AC Current Sensor Class 0.5 | 10/5A to 5000/1A Premium Current Transduction Technologies: Maximum Reliability for Energy Auditing & Grid Safety Our Industrial Current Transformer (CT) Series offers a complete, high-performance portfolio of primary current sensing hardware for power distribution, switchgears, and energy management systems. Available in diverse mechanical footprints—including solid-core, snap-on split-core, rectangular busbar windows, and flexible Rogowski coils—our CTs seamlessly step down high-amperage AC primary currents into safe, standard 5A, 1A, or low-voltage mA/mV secondary outputs for meters, relays, and RTUs. FOUR UNIVERSAL HOUSING & GEOMETRY CONFIGURATIONS We offer four distinct physical structures to accommodate any new project layout or challenging on-site retrofitting condition: 1. Solid-Core (Closed-Loop) Current Transformers Design & Fit: Fully continuous, solid ring/donut core design providing maximum magnetic circuit sealing. Best For: Brand-new switchgear assemblies, factory-floor panel building, and OEM machinery manufacturing. Key Advantage: Unmatched long-term accuracy (up to Class 0.2s), superior linearity, and highly cost-effective for newly built infrastructure. 2. Split-Core (Open-Loop / Snap-On) Current Transformers Design & Fit: Engineered with a rugged, split magnetic core and an ergonomic heavy-duty hinge/latch mechanism. Best For: Power grid energy audits, efficiency upgrades, and retrofitting existing factory panels. Key Advantage: Zero-Downtime Installation. Snaps securely around live cables in seconds without cutting wires or interrupting plant power supply, saving massive labor costs. 3. Rectangular Window (Busbar) Current Transformers Design & Fit: Designed with wide, square, or rectangular inner apertures customized to match standard commercial copper busbars. Best For: Main distribution boards (MDBs), high-capacity generator outputs, and substation switchgear panels. Key Advantage: Slips perfectly over single or stacked copper bar configurations, ensuring excellent physical stability and optimal space utilization inside the cabinet. 4. Flexible Rogowski Coils (Air-Core Coil Transducers) Design & Fit: Rope-like, highly flexible air-core coils that can be wrapped around complex, thick, or irregular conductor bundles. Best For: Narrow or congested panel spaces, transient current/harmonic analysis, and ultra-high current monitoring (up to 10kA+). Key Advantage: Extremely lightweight, zero magnetic saturation risk, wide frequency response, and fits into tight spaces where traditional rigid iron-core CTs physically cannot go. TECHNICAL ADVANTAGES Exceptional Measurement Accuracy: Available in Class 0.2, Class 0.5, and Class 1.0 specifications, guaranteeing precise data logging for commercial sub-billing and revenue-grade power quality tracking. Superior Galvanic & Thermal Safety: Encased in self-extinguishing, flame-retardant UL94-V0 polycarbonate housings with excellent dielectric isolation (up to 3kV to 4kV AC), protecting equipment and operators. Wide Dynamic Transformation Ratios: Scalable selection matrix ranging from micro-loads (100/5A, 200/5A) to massive industrial transmission currents (up to 5000/5A or 5000/1A).
