ABB’s harmonic surveys help companies reduce the risk of harmonic distortion and ensure they comply with G5/4-1 recommendation.
ABB’s harmonic surveys help companies reduce the risk of harmonic distortion and ensure they comply with G5/4-1 recommendation.
The surveys, which are carried out by ABB or a member of its network of authorised value providers (AVPs), ensure companies understand their harmonics’ challenges and that they are complying with G5/4-1 recommendations.
 
Harmonics’ surveys look at all the potential risks are one of many services offered as part of ABB’s 20+20 vision for improving customer outcomes in the water industry. Caused by non-linear loads such as variable-speed drives and other rectifier technology, high harmonic currents and high harmonic voltage distortion can cause a wide range of problems, often causing disruption to business operations.
 
The monitoring equipment is connected typically for a week to record site conditions. Data gathered from the monitoring phase is then used to produce a comprehensive report that analyses harmonic levels and confirms compliance with the Energy Networks Association’s G5/4-1 engineering recommendation.
