Key IEC Standards for Current Transformers
The primary standard for instrument transformers was transitioned from IEC 60044 to the IEC 61869 series. For your specific product line, these are the critical benchmarks:
- IEC 61869-1: General requirements for all instrument transformers.
- IEC 61869-2: Specific requirements for Current Transformers (replaces the old IEC 60044-1).
- IEC 60076: While mainly for power transformers, parts of this standard apply to the oil and insulation used in your Outdoor Oil Cooled units.
