It adopts through-core structure and is cast with flame-retardant epoxy resin for excellent stability.
Made of high-permeability permalloy or nanocrystalline material, it features good linearity and high sensitivity.
It delivers superior balance performance and strong resistance to electromagnetic field interference.
The through-core current transformer is mainly applied in cable circuit environments. It features simple structure, compact size and flexible application. Multiple through-core inner diameters are available corresponding to different cable specifications of the main circuit, covering main circuit currents from 160A to 1000A.
This series meets the technical requirements for Class 0.5 accuracy. It also satisfies the strict balance characteristic requirements specified in the new national standard. The unbalanced current output can be better than 30mA, 10mA and 5mA, which greatly reduces false alarms caused by magnetic field interference from main circuit current and fully guarantees equipment reliability.
This series complies with GB 14287.2-2005 and GB 14287.2-2014.
