新IEEE标准-已被取代。 取代。本指南涵盖了干式配电变压器和电力变压器的一般建议，这些变压器的平均绕组温升分别为80℃、115℃和150℃，绝缘系统的最大最热点工作温度分别限制在150℃、185℃和220℃。包括10000 kVA以下的变压器。提供了具有浸渍绝缘系统的通风、非通风和密封干式变压器的建议。

New IEEE Standard - Superseded. Superseded. This guide covers general recommendations for the loading of dry-type distribution and power transformers that have 80°C, 115°C, and 150°C average winding rises, and insulation systems limited to 150°C, 185°C, and 220°C maximum hottest-spot operating temperatures, respectively. Transformers through 10 000 kVA are included. Recommendations for ventilated, nonventilated, and sealed dry-type transformers having impregnated insulation systems are provided.
