Operational limits up to 1,000 meters above sea level (with correction factors applied for higher altitudes).
Additional requirements for Low-Power Passive Current Transformers By downloading the Part 1 PDF, you gain
The IEC 61869 series replaces the older IEC 60044 series. It divides instrument transformer standards into two distinct categories: general requirements and specific product standards.
: To ensure safety, reliability, and standardized performance across the global power industry.
Access to the latest revisions, protecting your designs from obsolescence. Ensuring high accuracy for billing and system monitoring
Historically, different types of transformers (like current transformers and voltage transformers) were governed by separate, independent standards (such as IEC 60044-1 and IEC 60044-2). The IEC 61869 series consolidated these older standards into a unified framework. Part 1 acts as the "umbrella" standard, containing rules that apply universally across the product line.
