Iec 61869-1 Pdf | Real & Reliable

The standard covers the design, construction, testing, and performance requirements for these instrument transformers, ensuring that they meet specific safety and accuracy standards.

While specific accuracy classes are detailed in part 2 (CTs) and part 3 (VTs), the general standard outlines the principles of accuracy testing, including burden, power factor, and frequency variation effects.

IEC 61869-1, titled "Instrument transformers – Part 1: General requirements," is an international standard that defines the common characteristics, safety rules, and testing procedures for all types of instrument transformers.
