ГОСТ 7746-2015

Current transformers. General specifications

Трансформаторы тока. Общие технические условия

Status: Effective - Supersedes. IUS 12-2016

The standard applies to electromagnetic current transformers (hereinafter referred to as transformers) of rated voltage from 0.66 to 750 kV inclusive, intended for transmitting the measurement information signal to measurement, protection, automation, alarm and control devices in AC electrical circuits with a frequency of 50 or 60 Hz, developed after 01.01.2016. Additional requirements for certain types of transformers in connection with the specifics of their design or purpose (for example, for cascade transformers, transformers, Designed for operation with normalized accuracy in transient conditions, transformers for installation in complete switchgear (KRU), phase-wired current-carrying conductors, combined) should be installed in standards, technical conditions, contracts or contracts for transformers of specific types. The standard does not apply to laboratory transformers, zero-sequence, summing, blocking, saturating.

Стандарт распространяется на электромагнитные трансформаторы тока (далее - трансформаторы) на номинальное напряжение от 0,66 до 750 кВ включительно, предназначенные для передачи сигнала измерительной информации приборам измерения, защиты, автоматики, сигнализации и управления в электрических цепях переменного тока частотой 50 или 60 Гц, разработанные после 01.01.2016 г. Дополнительные требования к отдельным видам трансформаторов в связи со спецификой их конструкции или назначения (например, для каскадных трансформаторов, трансформаторов, предназначенных для работы с нормированной точностью в переходных режимах, трансформаторов для установки в комплектных распределительных устройствах (КРУ), пофазно экранированных токопроводах, комбинированных) следует устанавливать в стандартах, технических условиях, договорах или контрактах на трансформаторы конкретных типов. Стандарт не распространяется на трансформаторы лабораторные, нулевой последовательности, суммирующие, блокирующие, насыщающиеся.
