IEEE P2938/D3.2, Jul 2022

IEEE P2938/D3.2, Jul 2022 is a draft guide focused on economic loss evaluation for sensitive industrial customers affected by voltage sags. It addresses how voltage disturbances can interrupt production, degrade process reliability, and create measurable financial impact in power, energy, and industry applications. This technical document is useful for organizations that need a structured way to assess outage-related costs, compare mitigation options, and support more informed engineering and procurement decisions.

IEEE P2938/D3.2, Jul 2022 overview

IEEE P2938/D3.2, Jul 2022 provides guidance for evaluating the economic consequences of voltage sags on industrial operations that are especially sensitive to power quality events. Its draft scope centers on translating electrical disturbance impacts into cost terms that can be used in planning and decision-making. For facilities and engineers working in power, energy and industry applications, the guide can help connect electrical performance with production loss, process interruption, and business risk in a practical way.

Typical use cases

This standard is typically relevant when assessing voltage sag exposure in manufacturing lines, continuous-process plants, and other industrial facilities where even brief disturbances may cause scrapped product, equipment stoppage, or restart delays. It may also support studies comparing mitigation measures such as ride-through capability, process hardening, or power quality improvement. Organizations responsible for facility reliability, industrial power systems, and project justification can use it to estimate likely loss scenarios and prioritize protective actions.

Why this standard matters

The value of IEEE P2938/D3.2, Jul 2022 lies in helping teams evaluate voltage sag impacts using a more consistent and defensible approach. That can improve design control, cost justification, and risk reduction when selecting electrical solutions for sensitive loads. It also supports clearer communication between operations, engineering, and procurement by giving a common framework for discussing expected losses and performance needs. For industrial users, this can be important when deciding whether mitigation is justified by the potential economic benefit.
