Based on the highest voltage for equipment ( Umcap U sub m

To ensure global compatibility, safety, and reliability, the International Electrotechnical Commission (IEC) developed the IEC 61869 series. At the core of this series is , which outlines the general requirements for all types of instrument transformers.

Standard ranges generally span from -5°C to +40°C for indoor installations, and -25°C or -40°C to +40°C for outdoor installations.
