IEEE Application Guide for AC High-Voltage Circuit Breakers Rated on a Symmetrical Current Basis

Timothy L. O'Hearn, PE


Course Outline

This 9-hour course will cover the application of indoor and outdoor high-voltage circuit breakers rated in accordance with the methods given in IEEE Std C37.04-1999, listed in IEEE Std C37.06-1997, and tested in accordance IEEE Std C37.09-1999.  Circuit breakers rated and manufactured to meet other standards should be applied in accordance with application procedures adapted to their specific ratings or applications.

This guide covers the application of indoor and outdoor high-voltage circuit breakers rated above 1,000 V for use in commercial, industrial, and utility installations.  It deals with usage under varied service conditions, temperature conditions affecting continuous current compensation, reduced dielectrics, reclosing derating as applicable, calculation of system short-circuit current, compensation at different X/R ratios, detailed calculations with application curves, out-of-phase switching, and general application.  The course materials are based entirely on IEEE C37.010-1999 (R2005) Application Guide for AC High-Voltage Circuit Breakers Rated on a Symmetrical Current Basis.  It will be necessary for the student to obtain a copy of IEEE C37.010-1999 (R2005).

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
