摘要： PURPOSE: A measure method and a device of a three phase instrument transformer ratio error test are provided to reduce measurement time by accurately measuring a secondary current. CONSTITUTION: A main body(30) collects, compares, and calculates various data. The main body display, stores, and outputs data. A first current detector measures a current. The first current detector comprises a switch. A wireless communications unit of a first current detector receives a starting signal of the main body. The wireless communications unit measures a primary current. A second current detector comprises a low voltage hook meter(21). The second current detector transfers a measured current value from the main body to a wire.
