用于电力变压器，包括电抗器和HVDC变压器，已组装并列出。针对所有单独的需求（参数），给出了设计和服务重要性的相关指数，以及验证状态。所有参数都指定给以下类别之一: -一般（物理/化学）-介电/绝缘-热/冷却-老化和稳定性-液-固系统-材料相容性购买时可用的所有电流修正均包含在本文件的购买中。

for use in power transformers, including, for example, reactors and HVDC transformers, are assembled and listed. A relevance index of importance for design and for service as well as the status of validation is given for all individual requirements (parameters). All parameters are assigned to one of the following categories: — General (physical / chemical)— Dielectric / Insulation— Thermal / Cooling— Ageing and Stability— Liquid-solid system— Material compatibilityAll current amendments available at time of purchase are included with the purchase of this document.
