About This Item
IEEE C62.22-1991 is a technical guide for the application of metal oxide surge arresters in AC systems. It helps engineers and specifiers determine how these devices may be selected and applied to protect power equipment from overvoltage conditions. In power, energy and industry applications, that guidance supports safer insulation coordination, better system reliability, and more consistent arrester application across different AC installations.
What is IEEE C62.22-1991?
IEEE C62.22-1991 provides application guidance rather than a product design specification. Its focus is the practical use of metal oxide surge arresters on AC systems, where surge protection must be matched to system voltage, operating conditions, and equipment insulation needs. The standard is intended to support engineering decisions for arrester selection, placement, and coordination so the device performs as intended under transient overvoltage events.
Where is IEEE C62.22-1991 used?
This standard is commonly used in AC power systems where metal oxide surge arresters are applied to protect transformers, switchgear, cables, and other connected equipment. It is relevant in utility networks, industrial power distribution, and facilities with exposed electrical installations that may face switching or lightning surges. Engineers and maintenance teams may use IEEE C62.22-1991 when planning protection schemes, reviewing equipment ratings, or checking arrester application practices.
Why is IEEE C62.22-1991 important?
IEEE C62.22-1991 matters because correct surge arrester application can reduce equipment stress, limit insulation failure, and improve overall system reliability. For procurement and engineering teams, it offers a consistent basis for comparing arrester use against system requirements and operating conditions. Using the guide can also support more careful design control, helping reduce the risk of misapplication in AC power systems where transient surges can cause costly damage or outages.
