What is the IEEE 519 1992 and 2014 ?

Title: IEEE 519: The Most Up-to-Date Standard for Harmonic Control

The power system is an essential part of our daily lives, and it is responsible for providing clean and reliable power to homes, businesses, and industries. However, power systems are often affected by various sources of harmonic distortion, including nonlinear loads such as variable frequency drives, power electronic equipment, and even renewable energy sources. If not properly controlled, harmonics can lead to numerous issues, such as increased losses, interference with communication systems, equipment malfunctioning, and reduced system capacity.

The IEEE 519 standard, also known as the "IEEE Std 519-1992," is a widely accepted standard for the control of harmonic distortion in power systems. The first edition of IEEE 519 was published in 1992 and introduced important provisions for harmonic control. This edition primarily focused on limiting harmonic voltages and currents at specific points in power systems, such as utility substations, industrial plants, and commercial facilities. It specified maximum allowed harmonic distortion levels based on the total short-circuit capacity of the system.

The 2014 Edition of IEEE 519: The Future of Harmonic Control

In 2014, IEEE 519 underwent a significant revision to address changing technological advancements and industry practices. The updated edition expanded the scope by covering not only voltage and current distortion but also additional measures related to power quality. It introduced new limits for individual harmonics, interharmonic frequencies, and resonance conditions.
