・Developed under the technical guidance of JEMIC(JapanElectric Meters Inspection Corporation).
・It isconvenient to expand the area of current value in everycalibration works.

・High accuratesecondary current can be gained because of its two-stepstructured transformer with compensating coil.
・Output secondarycurrent in a accuracy of ratio error by 10ppm and phaseangle error by 10µradagainst primary current.

・5A input is transformed to secondary 5 mA, 10 mA, 20 mA and 50 mA current.
・In-Phase Error 20 ppm, Quadrature Phase Error 20μrad
