Abstract

An open-close micro current transformer is designed for the situation where power disconnection is not applicable and it can replace the conventional current transformer

realizing online installation. The open-close micro current transformer has a square core and a casing made of ferrite with a high permeability

flat cut and small air gap. According to the experimental analysis

it has the advantages of simple structure

convenient operation

high precision and good linearity. In the end

the measures to improve its precision are proposed.
