Selecting current transformers - Janitza electronics

Most frequently, x / 5 A current transformers are used. The majority of measuring devices have the highest precision class at 5 A. For technical and moreover economic reasons, x / 1 A current transformers are recommended with long measuring cable lengths. The line losses with 1-A transformers is only 4 % in comparison to 5-A transformers.
