    AI Overview
    For anti-DC current transformers (CTs) that accurately measure both AC and DC components (often called DC immune or AC/DC sensitive CTs), key suppliers include
    Carel Tech (Tianjin), Bender Inc., and specialists found on industrial directories like DirectIndustry, Thomasnet, and GlobalSpec, offering solutions for smart metering, power quality, and fault detection. These transformers use advanced materials like nanocrystalline cores for high linearity, distinguishing them from standard AC-only CTs, and are used in applications needing precise leakage/fault current monitoring in systems with rectified DC. 
    Key Suppliers & Brands: 
    • Carel Tech (Tianjin): Specializes in DC immune CTs that accurately measure AC and DC components, crucial for smart metering.
    • Bender Inc.: Offers LINETRAXX® AC/DC sensitive CTs for fault/leakage current measurement in AC/DC systems.
    • Vacuumschmelze (VAC): Provides advanced current transformers with nanocrystalline cores for high accuracy in smart meters (VAC is a component supplier to meter manufacturers).
    • DIXSEN: Offers AC/DC current transformers for various power measurement needs.
    • Accuenergy: Provides flexible Rogowski coils (RIKn) and other high-accuracy CTs for power quality, some suitable for mixed AC/DC environments. 
    Where to Find More: 
    • Industrial Directories: Thomasnet and GlobalSpec list manufacturers like Suncor Stainless (heavy-duty DC transformers) or those offering power/filtering chokes.
    • Specialty Manufacturers: Companies like Virginia Transformer Corp (large power) and Polycast International (epoxy cast) provide high-quality CTs for various needs, often with custom options. 
    What to Look For: 
    • "DC Immune CT" / "AC/DC Sensitive CT" / "Type B CT": These terms indicate the ability to handle DC offset.
    • High Linearity & Accuracy: Essential for distinguishing true AC from DC components, especially in leakage detection.
    • Application-Specific Designs: For smart meters, fault detection (EV chargers, solar), or specific industrial needs.
