EASA announces the publication of an update to AR200,现在命名为 Guide For The Repair Of Dry-Type 变形金刚. This guide outlines best practices for the repair of dry-type 变形金刚.

EASA AR200: Guide For The Repair Of Dry-Type 变形金刚EASA members adopt a customer service-centered mission encompassing various electrical apparatus repairs such as electric motors, 变形金刚, 控制, 电气故障排除和构造. cq9网站的 技术服务委员会 最近审查和广泛编辑的 AR200 guide in support of transformer repair services.

之前的版本 AR200 (2011年出版)的题目是 Guide For The Repair Of Power And Distribution 变形金刚. 像之前的版本, it embraced a broad scope of transformer repair that included liquid-filled distribution or power 变形金刚 up to 10 MVA and 69 kV and dry-type distribution and power 变形金刚 up to 5 MVA and 25 kV.

在准备这次更新时, the 技术服务委员会 chose to narrow the scope to the types of transformer repair activities usually found in EASA service centers (i.e., non-liquid-filled distribution dry-type 变形金刚 with high voltage windings up to 69 kV and rated less than 15,000 kVA). 毕竟, liquid-filled transformer repair and service is a specialty few members offer, with m任何 standards and best practices differing from those for dry-type 变形金刚. In recognition of cq9网站的 international membership, the updated procedures in the new version now reference both IEEE and IEC standards.

Non-members can purchase a downloadable PDF from EASA's online store.

Besides being helpful to the transformer repair and service efforts in m任何 EASA service centers, it continues to position EASA as the definitive source for best practices in the electrical apparatus repair industry.

AR200 guide was an effort of the AR200 Task Group and cq9网站的 技术服务委员会, thanks also go to EASA members who offered their comments and expertise. With a view of continual improvement as industry standards evolve, we welcome your feedback.
