A Practical & Effective Way of Applying IEEE Std 519-2014 Harmonic Limits.

Most electrical engineers today appreciate the need to control harmonics on their power distribution networks. If left uncontrolled, harmonics have been known to cause overheating of electrical equipment and create equipment operational problems due to high voltage distortion conditions. But as we get inundated with technical information and opinions on the topic, it becomes increasingly more difficult to determine how best to manage these harmonics.

With this in mind, we released a white paper to assist engineers and contractors understand what harmonic distortion is and how to prevent it in their designs.  

In this technical paper, we will discuss:

  • Recommended Harmonic Limits
  • Differences in the 2014 and 1992 Standards
  • IEEE Std Definitions
  • Why iTDD makes sense for Harmonic Current Limits
  • How can iTDD be calculated and how it is best applied
