If you're looking for a technical overview of IEC 61869-1 , the latest major update is the 2023 edition (2.0)
- Temperature range: According to the standard, instrument transformers should be able to operate within a temperature range of -5°C to +40°C (IEC 61869-1:2016, clause 5.1). However, for special applications, the manufacturer and user can agree on a different temperature range.
- Hot spot temperature: The standard requires that the hot spot temperature of the instrument transformer does not exceed 120°C (IEC 61869-1:2016, clause 5.5). The hot spot temperature is the highest temperature reached by any part of the transformer under normal operating conditions.
- Overload conditions: During short-term overload conditions (e.g., 2 hours), the instrument transformer can be subjected to higher temperatures, but the hot spot temperature should not exceed 140°C (IEC 61869-1:2016, clause 5.6).
