3、 Structure Introduction

This series current transformer is ABS flame-retardant plastic shell fully closed structure, It made the product less susceptible to moisture. Permeability material adopt toroidal core which via annealing testing to ensure products accuracy of 0.2 or 0.5. The application of Superconducting magnetic materials makes the product achieve the same volume level del 0.2 S or 0.5 S plan and Can make the products in a wide current of 1%-120% accurate measurement under load . The primary is P1 、P2,secondry is S1、 S2. When the primary current flows P1 to P2 , then the secondary current through the external circuit flows from S1 to S2 ，is subtractive polarity.

Special remind

1、 When a current is passed, not open the secondary circuit, or high-pressure generation

2、 The current transformer primary structure of three rows of holes
