How Does Voltage Optimisation Work?

Voltage optimization works by using electronic devices known as voltage optimization units (VOUs), which are installed between the incoming electrical supply and the internal electrical distribution system of a building.

• Voltage Reduction: A voltage optimization unit regulates the incoming voltage from the power supply by reducing it to the optimal level for the electrical appliances and systems inside the building.
• Maintaining Equipment Performance: Although the voltage is reduced, the voltage optimizer ensures that equipment continues to operate as intended. Many electrical devices, particularly motors, lighting, HVAC systems, and other appliances, work more efficiently at lower voltages, and they won't notice a difference in performance.
• Power Conditioning: Some voltage optimization systems also include power conditioning features, which clean up electrical noise or spikes (also known as harmonics) that could damage sensitive electronics or cause inefficiency.
• Feedback Mechanism: Many modern voltage optimizers are smart and capable of adjusting dynamically to fluctuations in the incoming voltage, maintaining the optimized output under varying conditions.

How Can Voltage Optimisation Save Money?

Reduced Energy Consumption

Reducing Voltage: By lowering the voltage supplied to equipment to the optimal operating level, voltage optimization reduces the overall power consumption of electrical devices. For instance, equipment like lighting, heating, and motors, which are common in commercial and industrial settings, often run more efficiently at a lower voltage.

Savings on Electricity Bills: Since less electricity is being consumed, businesses and homeowners can see a reduction in their electricity bills. The amount saved will depend on the size of the installation and the nature of the electricity load.

Improved Equipment Efficiency

Many types of electrical equipment (like motors, air conditioning units, and lighting systems) perform more efficiently at lower voltages. Voltage optimization ensures that they are running at the voltage level where they consume the least amount of energy while still providing the same level of performance. For example:

• Motors: Motors run more efficiently at lower voltages, meaning they will use less power, resulting in savings on energy costs.
• Lighting: Incandescent and fluorescent lighting systems often benefit from lower voltage, which results in less energy consumption.

Reduced Wear and Tear on Equipment

Over-voltage can lead to excess heat in electrical components, which causes them to wear out more quickly. By optimizing the voltage and ensuring it stays within the ideal range, voltage optimization systems can extend the lifespan of electrical equipment.

For businesses with high-value machinery or equipment, this could translate into significant savings in maintenance and replacement costs.

Lower Carbon Footprint

By reducing electricity consumption, voltage optimization systems not only save money but also help reduce carbon emissions associated with energy production. This is particularly important for businesses or organizations seeking to meet sustainability goals or comply with environmental regulations.

Reduced Demand Charges

In some regions, utilities charge based on the peak demand (the highest amount of power used over a certain period). By optimizing voltage and reducing the total energy consumption of the system, voltage optimization can help lower peak demand, potentially reducing demand charges on your electricity bill.

Improved Power Quality

Some voltage optimization systems also offer features like power conditioning (e.g., filtering electrical noise or harmonics), which can help protect sensitive equipment from power surges or fluctuations. This prevents costly damage to high-value electronics, servers, or machinery.
