) units to protect the environment and maintain dielectric integrity.

Requirements for liquid-filled or dry-type insulation, corrosion protection, and grounding terminals.

When designing, testing, or manufacturing a current transformer, you cannot rely on Part 2 alone. You must read in tandem with IEC 61869-2 to get the complete technical picture. Key Technical Dimensions Covered in the PDF
