Similarly , a luxury holiday resort in the state of Rajasthan , India , installed more than 50 ABB drives on the air handling units and pumps of its HVAC system . This is helping the resort save around 30 percent of its annual energy use .
Energy efficiency can help to reach the 40 percent emission reduction targets set in the Paris Agreement . Whereas the steps taken to improve these two HVAC systems may seem small , applying similar solutions in many buildings can collectively represent a giant step towards a much more environmentally sustainable society .
Mitigating harmonics in critical applications All power networks have some level of distortion in them – with one of the most common types of distortion being harmonics . This introduces losses in the network which waste energy and increase costs . Harmonics can also cause interference to sensitive electrical equipment , resulting
in damage to network efficiency and reliability . This can lead to severe problems for critical applications in environments such as hospitals , utilities , and data centres .
Due to the inherent way traditional drives consume electrical energy , they commonly introduce harmonics into the supply network . ABB has solved this challenge by developing special ultra-low harmonic ( ULH ) drives . They require no complex filters , multipulse arrangements or special transformers to reduce harmonics , since they produce hardly any harmonics in the first place .
Using the power of digitalisation Innovative improvements do not end with hardware . Digital services associated with modern technologies enable operators to identify and address inefficiencies . With remote connections , sensors , and services , systems can provide real-time data on energy use , performance , and the condition of rotating electrical equipment .
