Miniature current transformers

1. The basic function of current transformersThe current transformers can convert primary currents with larger values to secondary currents with lower values through a certain transformation ratio, which are used for protection and measurement purposes. For example, a current transformer with a transformation ratio of 400/5 can convert the actual 400A current to 5A current.2.…
