CTPROXT250SELV概述

    CT Current Transformers: A Comprehensive Guide
    Product Introduction
    CT current transformers are essential devices designed to measure electrical parameters indirectly, particularly when the network current exceeds the rated current measurement range of conventional instruments. These transformers play a critical role in enhancing energy efficiency, reducing consumption, and improving overall system performance. Ideal for both civil and industrial applications, they are integral to ensuring the reliability, safety, and sustainability of electrical systems.
    Key Features:
    - Functionality: Used primarily for indirect measurement of current in sub-distribution switchboards, power centers, and other complex electrical networks.
    - Applications: Suitable for industries requiring precise energy monitoring and optimization, including residential, commercial, and industrial sectors.
    Technical Parameters
    Below are the key technical specifications for CT PRO XT and CT MAX series transformers:
    | Parameter | Value |

    | Standard Secondary Current | 5 A |
    | Maximum Operating Voltage | 1.2 kV |
    | Test Voltage | 3 kV at 50 Hz for 1 minute |
    | Short Circuit Rated Thermal Current | 40 A for 1 sec, 60 A for 1 sec |
    | Short Circuit Rated Dynamic Current | 2.5 kA for 1 sec |
    | Permanent Overload Rating | 1.2 times the rated current |
    | Frequency Range | 50-60 Hz |
    | Operating Temperature | -5°C to +50°C |
    Additionally, these transformers feature:
    - Integrated electronic protection circuits for SELV versions.
    - Flexible assembly systems, minimizing installation time.
    - Sealed covers for billing applications.
    - Compatibility with DIN rail, cable, or busbar mounting configurations.
    Product Characteristics and Advantages
    CT PRO XT and CT MAX series transformers stand out due to their robust design and advanced functionalities:
    - Compact Size: Enables seamless integration into switchboards and panels, saving valuable space.
    - Advanced Protection: Automatic secondary terminal protection prevents risks from open circuits, ensuring operator and device safety.
    - Ease of Installation: Screwless terminals simplify wiring, while clear assembly instructions enhance user experience.
    - Durability: Constructed with self-extinguishing thermoplastic materials and brass terminals, ensuring long-term reliability.
    - Compliance: Meets international standards such as IEC EN 60044-1 and IEC EN 61010-1.
    Application Scenarios and Usage Recommendations
    These transformers find applications across diverse sectors:
    - Industrial Settings: Monitoring energy usage in factories and power centers.
    - Residential Uses: Supporting sub-metering in apartments and utilities.
    - Utility Billing: Providing accurate measurements for billing and regulatory compliance.
    For optimal performance:
    - Always connect the primary and secondary cables correctly, following the marked directions.
    - Ensure proper earthing to avoid electrical hazards.
    - Use short-circuiting devices if measuring instruments detach temporarily.
    Compatibility and Support
    The CT PRO XT and CT MAX series transformers are compatible with various ABB measurement devices and systems, ensuring smooth integration. Manufacturers provide comprehensive support, including detailed manuals and customer assistance.
    Common Issues and Solutions
    Some typical issues users may encounter include:
    - Overvoltage: Addressed by the integrated secondary protection circuit, which limits residual voltage to below 25V RMS.
    - Incorrect Wiring: Follow the provided wiring instructions meticulously.
    - Improper Installation: Consult the installation sequence guide for step-by-step guidance.
