IEEE PC37.100.2/D5, May 2015 is a draft standard for common requirements used when testing AC capacitance current switching devices over 1000V. It addresses the testing conditions and expectations that help evaluate how these high-voltage switching devices perform in power equipment applications. For manufacturers, test laboratories, and specifiers, IEEE PC37.100.2/D5, May 2015 provides a technical reference that supports more consistent assessment of switching behavior, electrical performance, and related safety considerations.

IEEE PC37.100.2/D5, May 2015 overview

This draft document focuses on common requirements for testing AC capacitance current switching devices intended for systems above 1000V. In that context, it helps define a shared basis for evaluating device performance under switching and test conditions that may affect insulation, current interruption behavior, and operational reliability. Because the standard is tied to power and energy equipment, it is especially relevant where consistent test methods are needed to compare designs, verify ratings, and support engineering review.

Typical use cases

IEEE PC37.100.2/D5, May 2015 is typically used when specifying or verifying switching devices for higher-voltage AC installations, especially where capacitive current switching is part of the application. It may support laboratory qualification work, design validation, and procurement review for components used in substations, switchgear, and related electrical apparatus. The document is also useful when test teams need a common reference for determining whether a device meets expected performance during controlled switching tests.

Why this standard matters

This standard matters because testing requirements for high-voltage capacitance current switching devices can influence safety, reliability, and comparability across products. Using a common technical basis helps reduce ambiguity in acceptance testing and design verification, which is important for equipment operating over 1000V. It can also support clearer procurement language and better coordination between manufacturers, buyers, and test facilities, especially when performance results must be assessed against the same expectations.
