scope:

This guide provides a method to evaluate the economic loss impact of voltage sags on sensitive industrial customers. It describes how to carry out cost and loss economic-assessment of voltage sags, what economic indexes and assessment flowcharts can be considered, how to efficiently collect useful data for evaluation, and recommended experimental methods for testing users' equipment and production line.

Purpose

The purpose of this guide is to provide a technique for evaluating economic-losses of sensitive industrial customers caused by voltage sags, and further provides mathematical means, e.g., economic indexes and assessment flowcharts, to quantify the losses of sensitive customers.
