100A 300A 600A/5A Current Transformer For Energy Monitoring And Power Meter

A Current Transformer (CT) is a precision instrument designed to produce a reduced current in its secondary winding that is proportional to the AC current in its primary conductor. By scaling down high-amperage primary currents to standardized, measurable levels (typically 1A or 5A), CTs allow for the safe monitoring and protection of electrical systems without requiring high-power metering equipment. Whether used in high-voltage switchgear or compact smart meters, our current transformers provide the critical link between the power grid and sensitive control electronics.

• Superior Accuracy Classes: Available in various precision grades, including Class 0.1, 0.2s, 0.5, and 1.0, ensuring reliable data for everything from revenue-grade billing to general industrial monitoring.
• High-Permeability Core: Utilizing premium Silicon Steel or specialized Permalloy cores, our CTs exhibit exceptional linearity and minimal phase shift across a broad dynamic range.
• Flame-Retardant Enclosure: Housed in high-strength, UL94-V0 rated polycarbonate or ABS plastic, providing excellent mechanical durability and electrical insulation.
• Standardized Secondary Output: Optimized for a wide variety of secondary signals, including 5A/1A for traditional meters and 333mV/mA for low-power IoT energy sensors.
• Broad Range of Designs: Offered in Split-core (for retrofit installation), Solid-core (for new builds), and Busbar-mounted configurations to suit diverse physical environments.

• Energy Management Systems (EMS): Provides the data input for industrial power meters and sub-metering modules in factories and commercial buildings.
• Relay Protection: Critical for detecting overcurrent, ground faults, and short-circuit conditions to trigger circuit breakers in protection relays.
• IoT & Smart Grids: Integral for real-time current sensing in cloud-connected energy monitors and smart distribution boxes.
• Motor Control Centers (MCC): Monitors the load current of heavy-duty induction motors to prevent overheating and mechanical failure.

• Enhanced Operational Safety: Provides complete Galvanic Isolation between high-power primary lines and secondary monitoring circuits, protecting both equipment and operators.
• Ease of Installation: Our Split-core models feature a snap-on mechanism that allows for installation without disconnecting power cables, significantly reducing labor costs and system downtime.
• Exceptional Thermal Stability: Designed with high-grade insulation (Class B or F) and robust core geometry to ensure consistent performance even under significant ambient temperature fluctuations (-25 °C to +70°C).
• Long-Term Reliability: Every unit undergoes rigorous dielectric and ratio testing to ensure a maintenance-free service life of over 15 years in demanding industrial environments.
