Voltage optimisation solution

• Installs after the main switch of the entire facility or at a specific electric board
• Dynamically controls and stabilises the voltage provided to all loads in the facility, generating immediate energy savings
• Improves power quality and reduces maintenance costs

The Energy Guardian Voltage Optimisation Energy Saving Solution (“VOESS” for short) is a simple-install product that drops the voltage across your site by, on average, 10%.

Common sense tells us that running devices at this lower voltage will save energy, and the solution typcially generates savings of up to 18%.

What is Voltage optimisation and regulation?

The main voltage supplied by utilities typically fluctuates in the range of ± 10%. Voltage level depends on demand for electricity, quality of the electric infrastructure and distance of the site from the main transformer. Voltage fluctuations, especially overvoltage, can negatively affect electric appliances, lighting equipment and electronic devices. VOESS dynamically controls the voltage level, ensuring the right level of supplied voltage, preventing equipment failures and extending their lifetime.

Electric equipment and appliances available in the market are designed to work at the range of nominal voltages, which vary at different regions from over 240V and sometimes below 220V. High voltage causes inefficient use of equipment, increased losses and energy waste. VOESS regulates the supplied voltage, improving overall energy efficiency by reducing the voltage by up to 20V and stabilising it at the level where equipment will work most efficiently. Operating electric equipment at reduced and stabilised voltages generates around 18% energy savings. In addition, VOESS lowers losses, decreases reactive energy and provides a quick return on your investment.

Next-generation technology and design

VOESS is the next generation in a line of energy efficiency, field-proven solutions from Enistic. The VOESS system is built around a patented technology that enables dynamic control of the voltage supplied to electric circuits. The core of the system is based on a proprietary topology of power transformers controlled by a microprocessor. Unlike multi-tap autotransformer systems, VOESS is a cost-effective, highly reliable, small-footprint solution that does not compromise on power quality when providing energy efficiency.

Improved power quality

VOESS is a “Power Quality Friendly” system. VOESS supplies a pure sinusoidal waveform to all electric circuits; it is harmonics-free and has next to zero THD. Even more, VOESS mitigates and filters out harmonics and voltage distortions, reducing electric equipment failures. Regulating voltage for inductive loads such as air conditioners, compressors and pumps helps reduce reactive power (KVAR), contributing to the environment and minimising the risk of utility penalties.

High reliability

Unlike systems based on solid state components that require special thermal management considerations, VOESS’s durable design guarantees the highest degree of robustness; it can tolerate disturbed electric environments and sustain any harsh ambient conditions. To further eliminate any risk of failure, VOESS includes built-in protection mechanisms, internal and manual bypass and output circuit protection.

Easy and quick installation

VOESS is installed after the main circuit breaker of the facility, supplying electricity for all circuits and loads. Due to its small footprint it can even be wall-mounted and connected to specific electric panels that supply electricity to certain parts of the site, e.g. a floor in an office building. The specification and selection of the right VOESS model is simple, requiring only matching VOESS’s rating to the incoming circuit breaker. The VOESS installation does not require any changes of existing electric infrastructure or wiring.

Supports all loads

Since VOESS reduces and stabilises the supplied voltage, you benefit from immediate savings. Each load type generates a range of savings, for example:

Savings

Total energy savings in facilities with the above equipment can average 10 to 18% off their annual electricity bill. Voltage reduction will further improve performance of appliances with AC motors, such as air conditioners, compressors, pumps, etc. For these systems, VOESS reduces the electric operating current and improves the power factor, resulting in a decrease in the electric infrastructure losses.

Price and Return on Investment

VOESS can be installed on most commercial premises. Smaller systems are targeted at small to medium offices, light commercial or light manufacturing plants. Systems for these type of premises can be provided on a fixed cost basis. Systems for larger properties, where the power being used is typically in excess of 240 kVA, are supplied on a project-by-project pricing basis.
