scope:

This document revises the application guide for capacitance current switching for high-voltage circuit breakers rated in accordance with IEEE Std C37.04™ 1 and listed in IEEE Std C37.06™. It supplements IEEE Std C37.010™¹ Circuit breakers rated and manufactured to meet other standards should be applied in accordance with application procedures adapted to their specific ratings.

Purpose

This guide is intended for general use in the application of circuit breakers for capacitance current switching. Familiarity with other US national standards applying to circuit breakers is assumed, and provisions of those standards are indicated in this guide only when necessary for clarity in describing application requirements.

¹ Information on normative references can be found in Clause 2.
