Measuring transformers. Part 1. Technical conditions for current transformers

Трансформаторы измерительные. Часть 1. Технические условия на трансформаторы тока

Status: Effective - Introduced for the first time till 01.01.2022. IUS 1-2019

The standard applies to measuring transformers with voltage from 3 to 750 kV, intended for use in electrical circuits of alternating current with frequency of 50 and 60 Hz for the purpose of transmitting the signal of measurement information to measuring, protection, automation, alarm and control devices developed after January 01, 2019. Requirements for certain types of transformers in connection with the specifics of their design or purpose are established in standards, technical documentation, contracts or contracts for transformers etnyh types. The standard does not apply to laboratory, zero-sequence, summing, blocking and saturating transformers.

Стандарт распространяется на измерительные трансформаторы напряжением от 3 до 750 кВ, предназначенные для применения в электрических цепях переменного тока частотой 50 и 60 Гц с целью передачи сигнала измерительной информации приборам измерения, защиты, автоматики, сигнализации и управления, разработанным после 01 января 2019 г. Дополнительные требования к отдельным видам трансформаторов в связи со спецификой их конструкции или назначения устанавливают в стандартах, технической документации, договорах или контрактах на трансформаторы конкретных типов. Стандарт не распространяется на лабораторные, нулевой последовательности, суммирующие, блокирующие и насыщающиеся трансформаторы.
