About This Item
IEEE C57.13.2-1991 is a technical standard for conformance test procedures for instrument transformers, giving utilities, engineers, and test labs a structured way to evaluate performance against expected requirements. Focused on power, energy and industry applications, it supports consistent verification of measurement devices used in current and voltage circuits. By defining how testing should be approached, IEEE C57.13.2-1991 helps improve comparability, confidence in results, and acceptance of instrument transformer products.
About IEEE C57.13.2-1991
This standard provides conformance test procedures specifically for instrument transformers, which are commonly used to scale high electrical quantities for metering, protection, and related power-system tasks. IEEE C57.13.2-1991 is intended to guide technical evaluation so that test results are repeatable and can be applied consistently across equipment and laboratories. As an inactive standard, it remains relevant as a reference for legacy systems, documentation review, and historical compliance work in electrical engineering environments.
Where is IEEE C57.13.2-1991 used?
IEEE C57.13.2-1991 is typically used in test facilities, utility engineering groups, and manufacturing or quality-control workflows involving instrument transformers. Its procedures are relevant where current transformers and potential or voltage transformers must be checked for conformance before use in metering or protective relaying applications. In power, energy and industrial installations, the standard can support acceptance testing, specification review, and product qualification for equipment that must deliver reliable measurement performance.
Importance in practice
In practice, IEEE C57.13.2-1991 matters because instrument transformers influence measurement accuracy and system protection performance. Clear conformance test procedures help reduce ambiguity during procurement, factory testing, and field verification. They also support better design control by giving manufacturers and users a common basis for evaluating performance and comparing results. For organizations managing electrical assets, the standard can help limit risk, improve consistency, and document technical compliance more effectively.
