When a short-circuit fault occurs, the short-circuit current is usually several times larger than the normal load current, or even dozens of times. Such a large short-circuit current will cause great mechanical stress and thermal effects, which is harmful to the current transformer.

Therefore, when selecting the current transformer, in addition to the capacity and insulation performance should meet the requirements, the mechanical stress and thermal effect during the short-circuit fault should also be checked so that it does not exceed the rated control value of the current transformer.
