Acrel AKH-0.66 / K Split Core Current Transformer

Acrel AKH-0.66/K series split core type current transformers are mainly used in reconstructing projects of urban and rural power grids. The split core current sensors can be mounted easily without the removal of the primary bus. They also can be operated with electricity, which prevents the normal utilization of electricity.

Acrel AKH-0.66/K SCT current transformers series save manpower, material resources, and financial resources and improve the efficiency of users. These split CT transformers match with relay protection, measuring, and metering equipment.

  • Without removal of primary bus

  • Be operated with electricity

  • Save manpower

  • Varies dimension optional
