Variety and selection method of low voltage open type current transformer

1. Overview

Open type current transformer is also called open type current transformer or open type current transformer, mainly used in the transformation project, the distribution system has the advantages of convenient installation, without disassembly of a bus, can also be charged operation, does not affect the normal use of electricity customers, for the users of the project save manpower, material and financial resources, improve efficiency. The series current transformer can be used with relay protection, measurement and metering device.
