CTK-38 2.5-5VA Three Phase Circular Coil Structure Split Type Current Transformer

1.Product Description

CTK-38 2.5-5VA is a three-phase circular coil structure split iron core current transformer designed specifically for power system monitoring and protection. This product adopts an innovative split type iron core structure, which can be easily installed without continuous power supply, especially suitable for renovation projects or space limited distribution cabinet applications. Its circular coil design can adapt to cable installation in different directions, ensuring measurement accuracy is not affected by mechanical stress. This transformer provides a rated capacity of 2.5-5VA, with an accuracy level of up to 0.5, a working temperature range of -25 ° C to+70 ° C, and excellent anti magnetic saturation performance and long-term stability. Widely used in industrial distribution systems, commercial building energy metering, and new energy generation grid connection, providing reliable solutions for current measurement, energy metering, and relay protection. The characteristics of split design, high-precision measurement, and flexible installation make it an ideal choice for modern power system monitoring.

Function:
1. High precision current conversion: Using high-quality silicon steel cores and precision coil structures, it achieves precise conversion from a high current to a secondary standard current (5A/1A), with an accuracy level of up to 0.5.

2. Safety electrical isolation: Provide comprehensive electrical isolation protection, effectively isolate the high-voltage side from the measurement circuit, and ensure the safety of operators and equipment.

3. Flexible installation and maintenance: The unique circular coil split design supports live installation without disconnecting the main circuit, making it particularly suitable for renovation projects and installation in narrow spaces.

4. Intelligent monitoring support: Optional RS485 communication interface and Modbus protocol can be configured to seamlessly integrate with smart meters and energy management systems, enabling remote monitoring and data analysis.

5. Reliable protection function: Quickly respond to current changes, provide accurate signals for relay protection devices, and effectively prevent power faults such as overload and short circuit.
