An Introduction to 400 Hz Electrical Distribution Systems

J. Paul Guyer, P.E., R.A., Fellow ASCE, Fellow AEI

Course Outline

1. INTRODUCTION
2. GENERAL CONSIDERATIONS
3. DESIGN REQUIREMENTS

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

Learning Objective

Upon completion of this course you will:

• Learn about rotary converters and motor generator sets are used for both low and medium voltage systems;
• Learn how to employ solid state converters for low-voltage systems;
• Learn about flight-line electrical distribution sets (FLEDS) used in conjunction with the low-voltage or medium-voltage systems;
• Find out about the inductive contribution to the reactance voltage drop of 400-Hz systems which necessitates certain modifications to conventional distribution and utilization system design to compensate for the increased voltage drop.
• Learn about acceptable end-voltage requirements;
• Learn about maximum cable length limitations; and
• Learn the fundamentals of system layout.

Intended Audience
