IEEE P2938/D3, Nov 2022

IEEE P2938/D3, Nov 2022 is an approved draft guide focused on economic loss evaluation for sensitive industrial customers affected by voltage sags. It addresses a practical power-quality problem: how short-duration voltage reductions can interrupt processes, damage output, or create costly downtime. For engineers working in power, energy, and industrial applications, this standard helps frame a more consistent approach to assessing financial impact and comparing mitigation options.

About IEEE P2938/D3, Nov 2022

This technical document provides guidance for evaluating the economic losses associated with voltage sags at sensitive industrial sites. IEEE P2938/D3, Nov 2022 is relevant where process continuity, equipment ride-through, and production reliability are affected by disturbances on the supply system. Rather than defining a generic power system rule, it supports a structured way to estimate cost exposure and relate power-quality performance to operational consequences. That makes it useful in planning, analysis, and decision-making.

Where is IEEE P2938/D3, Nov 2022 used?

IEEE P2938/D3, Nov 2022 is commonly used in industrial facilities that depend on stable voltage to keep automated processes, drives, control systems, and sensitive production equipment operating. It can support electrical studies, power-quality investigations, and loss assessments for sites where even brief sags may disrupt manufacturing flow or product quality. The guide is also relevant when comparing mitigation measures such as conditioning equipment, process hardening, or utility-side improvements.

Importance in practice

In practice, this standard helps translate a voltage sag event into measurable business impact, which is valuable for compliance discussions, design review, and investment decisions. IEEE P2938/D3, Nov 2022 can support consistent evaluation methods, reduce uncertainty in loss estimates, and improve communication between engineers, plant operators, and procurement teams. By linking technical performance to economic consequences, it helps organizations prioritize mitigation where the risk of interruption is highest.
