Product Category Overview
Current Transformer
The wide-measuring-range micro Current Transformers (CTs), PTs and current/voltage transformers, grade S CTs, high-saturation-high-linearity DC immune CTs are specially designed for wide measuring-range electricity meters (such as the wide-measuring-range three-phase-three wire, three-phase-four wire electricity meters, anti-tampering electricity meters). Hongfa designs and produces CTs according to JB/T10665 standard for micro current transformer, JB/T10667 standard for micro voltage transformer.All CTs conform to IEC60044, JJG 313-1994 and GB/T 20840.2-2014 standards.
