Abstract

New IEEE Standard - Active. The basic principles, application objectives, functions, performances, and test methods for alternating current (ac) standard signal sources with digital output is outlined in this guide. Aan approach for preparing a specification for ac standard signal sources that provide standardized digital voltage/current output signals in the form of a formatted digital output stream is offered. These signals are used to simulate the output of an electronic instrument transformer or merging unit (MU) when testing intelligent electronic devices (IEDs). The purpose of this guide is to serve as a foundational specification, accompanied by informative annexes, intended to guide utilities, system integrators, manufacturers, and other related entities through defining the overall performance and application objectives of ac standard signal sources.
