High-Potential Test Requirements for Excitation Systems for Synchronous Machines
N 421.3
Annotation
This standard applies to high-potential testing of complete excitation systems and their components for synchronous machines. The components of the excitation system are described in IEEE Std 421.1™ [B2].1 Auxiliary devices connected to either the input or output side of the rectifier bridge are exposed to similar excitation system stresses and are included in the requirements of this standard. Examples of such devices include temperature indicators, transducers, meters, field circuit breaker, discharge resistor, crowbar, etc. This standard does not cover the synchronous machine field winding.
Purpose
The purpose of this standard is to provide requirements and specific directions for the high-potential testing of complete excitation systems and their components using the most recent information manufacturers have made available.

Требования испытания высокого напряжения для систем возбуждения для синхронных машин
Этот стандарт относится к высоко-потенциальному тестированию полных систем возбуждения и их компонентов для синхронных машин. Компоненты системы возбуждения описаны в Станд. IEEE 421.1™ вспомогательные устройства [B2].1, подключенные к любому, который сторона ввода или вывода выпрямительного моста представлена подобным системным усилиям возбуждения и включена в требования этого стандарта. Примеры таких устройств включают индикаторы температуры, преобразователи, метры, полевой выключатель, разрядный резистор, лом, и т.д. Этот стандарт не касается синхронной обмотки возбуждения машины.
