IEC 60076-24:2020适用于25kVA至3150kVA的中型电力变压器，最高电压适用于36kV以下的设备，或适用于低压（LV）网络，最高电压适用于配备调压装置的1.1kV以下的设备。调压配电变压器是指配有控制一次或二次电压的部件的变压器，用于有载调压。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制。VRDT必须作为降压和升压变压器正常工作。 本文件涵盖的变压器符合IEC 60076（所有部分）中规定的相关要求，除非本文件另有规定，否则还符合欧洲标准EN 50160和EN 50588-1。

IEC 60076-24:2020 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.
