本文件适用于25 kVA至3 150 kVA的中型电力变压器，最高 电压高达36 kV的设备，或电压最高的低压（LV）网络 高达1.1 kV的设备，配备有调压装置。 调压配电变压器是指配有以下部件的变压器: 控制一次或二次电压，以便进行有载调压。 安装VRDT的主要目的是调节低压电网电压水平（即。 400 V），以避免违反相关标准或法规规定的限值。VRDT 必须作为降压和升压变压器正常运行。 本文件涵盖的变压器符合 除非本文件另有规定，否则IEC 60076（所有部分）也符合 欧洲标准EN 50160和EN 50588-1。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This document applies to medium power transformers from 25 kVA up to 3 150 kVA with highest voltage for equipment up to 36 kV, or in low voltage (LV) networks with highest voltage for equipment of up to 1,1 kV equipped with voltage regulating devices. Voltage regulating distribution transformers are transformers equipped with components to control primary or secondary voltage for on-load voltage regulation purposes. The main objective of the installation of a VRDT is to regulate the LV network voltage level (i.e. 400 V), to avoid violation of the limits defined by relevant standards or regulations. The VRDT must operate properly as a step down and step up transformer. Transformers covered by this document comply with the relevant requirements set out in IEC 60076 (all parts) and, unless otherwise stated in this document, they also comply with European Standards EN 50160 and EN 50588-1.All current amendments available at time of purchase are included with the purchase of this document.
