AKH -0.66K series open-type current transformers are mainly used in industrial urban and rural power grid reconstruction projects.
They are easy to install and do not need to disassemble the primary busbar. They can also be used for live measurement and metering devices. operation, without affecting the normal electricity consumption of customers, saving manpower, material and financial resources for user transformation projects, and improving efficiency. This series of current transformers can be used in conjunction with relay protection measurement and metering devices.
