High-Accuracy Current Transformers – Split-Core & Rogowski CTs for AC Monitoring
hqsensing provides a wide range of split-core current transformers and flexible Rogowski coils, engineered for fast installation and high-accuracy measurement from low to high AC currents. Our CTs support Class 0.2S and 0.5S instruments as per IEC 61869-2, IEC 62053-22, and ANSI C12.20, delivering minimal phase angle error for precise power and energy monitoring. All models are certified with UL/EN/CSA 61010-1, UL 2808 listing, CE, and RoHS 3, ensuring compliance with the latest NEC 2017 code and global safety standards for field-installed CTs.
Choose the Right Current Transformer (CT) for Energy Monitoring Selecting the right CT split-core, flexible Rogowski coil, or solid-core is key to accurate AC current measurement and efficient energy monitoring. Consider accuracy class (e.g., 0.2S), primary current rating, conductor size, and output connection type (cable, terminal, or RJ12). Proper CT selection ensures compliance with IEC 61869, ANSI C12.20, and UL 2808 standards, enhancing system accuracy, safety, and installation efficiency.
