Measure small or large AC current with high accuracy using split-core CT, solid-core CT or Rogowski coil solutions
For over 15 years, we have developed a large portfolio of AC measurement devices, including current transformers, hall sensors, and Rogowski coils. The reliability, ease of use, and great value of YHDC AC measurement products make them ideal solutions for various applications and industries.
Versatile current measurement solution that is suitable for both new and retrofit applications. Rated input current ranges from 10A up to 5kA. Various window sizes and shapes are available, which allows YHDC split-core CTs to be used in many scenarios.
Are similar to CTs in the sense that the loop can be opened and closed easily. Rogowski coils have unique advantages including:
• Ability to measure currents up to 500kA
• Responds to fast-changing currents down to 1 μs
• Low construction cost
Rogowski coils output a voltage signal that is proportional to primary current in magnitude but also 90° out of phase. Therefore, an integrator must be used in conjunction if phase is of concern.
