IEEE 28-1972

IEEE 28-1972 is a superseded technical standard for surge arresters, also called lightning arresters, used on alternating current power circuits. It addresses the design and application context for protective devices intended to limit overvoltage stress on electrical equipment. In power, energy and industrial systems, this kind of standard matters because it helps define a common basis for selection, performance expectations, and system protection practices.

What is IEEE 28-1972?

IEEE 28-1972 is a standard focused on surge arresters for AC power circuits, providing a technical framework for devices that divert abnormal voltage surges away from sensitive equipment. In practical terms, it helps define how these arresters relate to insulation coordination, operating duty, and protective performance in electrical networks. As an IEEE standard, it is part of the engineering reference set used to support consistent specification and evaluation of arrester-related requirements in power systems.

Where is IEEE 28-1972 used?

This standard is most relevant in alternating current power installations where lightning or switching surges can threaten transformers, switchgear, lines, and other connected equipment. It may be used in utility distribution and transmission environments, as well as industrial power systems that rely on surge protection to maintain equipment integrity. IEEE 28-1972 is useful when engineers, specifiers, and purchasers need a common technical reference for arrester selection and application within electrical protection workflows.

Why is IEEE 28-1972 important?

IEEE 28-1972 matters because surge protection decisions affect both equipment reliability and system safety. A clear standard can support more consistent design choices, procurement specifications, and testing expectations for lightning arresters in AC circuits. It also helps reduce ambiguity when comparing protective devices or coordinating them with other electrical components. For organizations managing power systems, having a defined reference can improve documentation quality and lower the risk of mismatched protection practices.
