|The Green Grid, a global consortium of organisations dedicated to advancing resource efficiency in data centres, has announced the release of a new white paper focusing on data centre power system harmonics. |
The Green Grid report presents an overview of harmonics, including what they are, the difference between harmonic voltage and current, what causes harmonics, and what problems harmonics can cause. It also goes on to discuss what levels of harmonics can be tolerated and under what conditions, and suggests diagnostic and mitigation methods, as well as outlining how harmonic voltages and currents can affect data centre power distribution system efficiency.
Ian Bitterlin, EMEA Technical Work Group chair at The Green Grid, said: "There can sometimes be a danger of harmonics being overlooked when it comes to data centre efficiency, possibly because it can be perceived as a complex subject to understand. However, it has a major part to play in the health and effectiveness of data centres, and it is important for organisations to begin analysing whether their PSUs are affecting the power and efficiency of their systems.
"It is of particular importance to data centre owners who are advanced in their energy efficiency programmes. For example, when we are talking about taking a data centre's PUE down from 1.3 to 1.2, harmonics can be a sizeable contributor to success."
