IEEE - IEEE C57.13.6 - STANDARD FOR HIGH-ACCURACY INSTRUMENT TRANSFORMERS Organization: IEEE
Date: 2005-09-22
Description: There are two important differences about these new accuracy class definitions as they apply to routine current transformer test requirements: a) A low current test is required at 5% of rated current (0.25 A secondary), in lieu of the 10% of rated current test specified in IEEE Std C57.13. This test point corresponds with the light load test point of transformer rated electromechanical and solid state electricity meters as specified in ANSI C12.20.
