IEC 60076-15:20 15适用于三相和单相充气电力变压器（包括自耦变压器），但某些类别的小型和特殊变压器除外，例如: -额定功率小于1千伏安的单相变压器和小于5千伏安的三相变压器； -变压器，没有额定电压高于1 000 V的绕组； -仪表变压器； -安装在机车车辆上的牵引变压器； -启动变压器； -测试变压器； -焊接变压器。 IEC 60076-15的第二版取消并取代了2008年发布的第一版，构成了技术修订。与第一版相比，以下主要技术变化是: -根据IEC 60076的相关修订标准进行修改-1、IEC 60076-2、IEC 60076-3及《高压开关设备及控制设备》修订标准中SF6气体的相关条目； -增加了“替代冷却模式下的最小功率”条款； -增加了“安全、环境和其他要求”条款； -增加了“中性回路中的直流电流”条款； -增加了“电磁兼容性（EMC）”条款； -增加了“高频开关瞬变”条款。

IEC 60076-15:2015 applies to three-phase and single-phase gas-filled power transformers (including auto-transformers) with the exception of certain categories of small and special transformers such as:
- single-phase transformers with rated power less than 1 kVA and three-phase transformers less than 5 kVA;
- transformers, which have no windings with rated voltage higher than 1 000 V;
- instrument transformers;
- traction transformers mounted on rolling stock;
- starting transformers;
- testing transformers;
- welding transformers. This second edition of IEC 60076-15 cancels and replaces the first edition published in 2008 and constitutes a technical revision. The following main technical changes from the first edition are:
- Modified in accordance with the related revised standards of IEC 60076-1, IEC 60076-2, IEC 60076-3 and related items of SF6 gas in the revised standard of "High-voltage switchgear and controlgear;
- Added the clause "minimum power under alternative cooling modes";
- Added the clause "safety, environmental and other requirements";
- Added the clause "d.c. currents in neutral circuits";
- Added the clause "electromagnetic compatibility (EMC)";
- Added the clause "high frequency switching transients".
