Course description

In How Ambient Conditions Impact the Rating of Electrical Equipment, you'll learn ...

  • How altitude, temperature and humidity affect electrical equipment ratings
  • The types of electrical equipment that are impacted by ambient conditions
  • How to calculate derating factors for transformers, motors, VFDs, generators and other equipment

Overview

Credit: 1 PDH

Length: 19 pages

Electrical equipment which relies on air cooling is affected by the altitude, air temperature and humidity. This course provides the methodology for developing an estimate of rating factors for electrical equipment at various ambient conditions.

This course is not intended to replace or modify manufacturer's ratings or recommendations. Rather, the course provides guidance on estimating electrical equipment sizes for project cost and space requirements.

The course includes a spreadsheet that can be used to quickly estimate altitude rating factors for various types of electrical equipment.
