Harmonics solutions explained 

Harmonics are distorted electrical waveforms that introduce inefficiencies into your electrical system. They produce wasteful heat and can cause plant issues and fees from your local power company. So how do you identify them? How do you address them? What do you need to know? The Harmonic solutions explained white paper will provide you with these valuable insights and a whole lot more.

Stay in compliance with IEEE 519 recommendations

Failing to meet IEEE 519 standards for current distortion is a costly mistake. By placing the Harmonic Correction Unit at the location of harmonic distortion generating equipment you can gain the benefit of internal and external harmonic protection.
