Voltage optimization is a technique for controlling the voltage supplied to electrical equipment, usually by lowering it to a level that is more efficient to operate. It refers to the systematic and controlled lowering of voltages received by an energy consumer to reduce energy consumption, power demand, and reactive power demand. Some voltage ‘optimisation’ devices have a set voltage adjustment, whereas others automatically regulate the voltage.
Voltage optimisation systems are often installed in series with a building’s mains electrical supply, providing an optimum supply to all of its electrical equipment. In many electrical systems, the voltage provided by the grid fluctuates, occasionally surpassing the optimal level required by electrical equipment. This excess voltage can cause inefficiencies, higher energy use, and premature equipment failure. These systems are intended to address these concerns by stabilizing the voltage at a level more appropriate for the equipment in use.
There are two main types of voltage optimisation:
- Fixed voltage optimisation: This type of system reduces the incoming voltage to a fixed, pre-determined level. It ensures that the voltage supplied to the equipment remains within a specific range, typically resulting in energy savings and improved equipment performance.
- Variable voltage optimisation: These systems dynamically adjust the voltage based on real-time conditions such as the load on the system and the voltage supplied by the grid. This allows for even greater energy savings and can adapt to changes in the electrical system over time.
Advantages
It can provide several benefits including:
- Energy savings: By reducing the voltage supplied to electrical equipment, voltage optimisation systems can decrease energy consumption, resulting in lower utility bills.
- Extended equipment lifespan: Operating electrical equipment at the correct voltage can reduce stress on the components, leading to longer lifespans and reduced maintenance costs.
- Improved power quality: Stabilizing the voltage can improve the overall quality of the power supply, reducing the risk of voltage-related issues such as fluctuations or surges.
Voltage optimisation is commonly used in commercial and industrial settings where large amounts of electrical equipment are used, but it can also be applied in residential settings to achieve similar benefits.
