NEW PMI White Paper: An Overview of Harmonics and Power Quality

Check out our new white paper detailing harmonic distortion and how it affects power quality for utilities and end users.

Although distortion begins with harmonic currents drawn by end user loads, the utility is responsible for voltage quality as delivered to customers. 

The physics of voltage drop, nonlinear currents, and the practicalities of the electric distribution network make it impossible to eliminate harmonic distortion entirely.

The intertwined relationship between end-user load current and delivered utility voltage can create complex situations requiring detailed measurements and cooperation from all sides.

Some harmonic PQ issues present immediate symptoms due to nuisance equipment shutdowns or mis-operation, and some are hidden until equipment fails prematurely due to excessive heat.

Harmonics present complex engineering challenges, and understanding the issues surrounding harmonics is the first step to solving them.
