Model description
Technical parameters
1. Insulation requirements: The primary winding bears the power frequency voltage of 3 kW to the secondary winding and the ground as well as the secondary winding to the ground for 1 min, and the insulation resistance shall not be less than 10 MΩ.
2. The rated secondary current is 5 A. See the table below for the rated primary current, rated capacity and accuracy level.
Note: When the primary current is above 150 A (including 150 A), the core is penetrated by one turn by default. When the primary current is below 150 A, the composite turn can be selected to form a solid.
