Why winding temperature not measuring directly?

Winding temperature is often not measured directly due to the challenges associated with placing sensors within the winding itself, which can be intrusive and affect performance. Instead, indirect methods, such as measuring the temperature of the housing or using thermal models, are employed to estimate winding temperature. This approach minimizes disruption and allows for easier monitoring while still providing accurate temperature assessments. Additionally, indirect measurements can help in assessing temperature changes over time without interrupting the operation of the equipment.
