How does Static var generator reduce kva demand? A Static Var Generator (SVG) reduces kVA demand through the following mechanisms: 1. Dynamic Reactive Power Compensation Real-Time Adjustment: SVG provide real-time reactive power support by injecting or absorbing reactive power (kVAR) as needed. This dynamic response helps maintain voltage levels, reducing the overall kVA demand. 2. Improved Power ...
Harmonics: Not a Problem Unless They Become One Harmonics in modern power systems are now considered “the new normal” due to the widespread use of non-linear loads. While harmonics can lead to issues such as overheating, overloads, and resonance, they don’t always pose immediate problems. The key is understanding when harmonics are actually causing harm. When Should You Ac...
1. Introduction In light of high energy usage, environmental pollution, and rising fossil fuel prices, current dependence on internal combustion engine (ICE) technology employed in vehicles should be reduced, and the widespread use of electric vehicles (EVs) as the transportation of choice in 20 to 30 years' time should be increased. It is estimated that EV vehicle penetration will increase gradua...
