Voltage Regulation

Voltage regulation is a transformer-based technology which improves the power quality of your site.

By reducing the voltage supplied to your site, voltage regulation technology enhances your power resilience and saves electricity, reducing costs and CO2 emissions.

Powerstar’s voltage regulation solutions have online, remote monitoring capabilities, providing full visibility of asset performance, savings, and more.

How voltage regulation can help you

Spikes, sags or fluctuations in your voltage supply, or a consistent overvoltage can cause damage to equipment, disrupt operations and waste energy. Sudden changes in voltage can trip sensitive electrical equipment. Consistently supplying equipment with a higher voltage than required can cause damage or premature burnout.

Regulating, conditioning, and reducing your incoming voltage supply protects your electrical equipment while reducing electrical consumption, costs, and carbon emissions.

How does voltage regulation work?

The voltage of electricity supplied by the National Grid typically fluctuates. In order to meet their binding requirement of supplying users with 230V, the National Grid actually supplies a higher average voltage – typically around 245V – to ensure that the lowest value is still acceptable.

In the UK, electrical equipment is generally designed to work at 220V. This means that it is always operating at a higher voltage than necessary, which causes damage and reduces its working lifetime.

Powerstar uses patented technology to achieve the voltage reduction, which is far more efficient than other voltage regulation or voltage optimisation solutions. Traditional solutions transform the entire voltage supplied to a site, and thus suffer large losses. The Powerstar solution transforms only the reduced voltage and therefore loses far less energy in doing so.

The technology can either provide a set level reduction for high, but stable incoming voltage profiles, or can dynamically regulate a fluctuating voltage profile to maintain a desired set level.

How to implement voltage regulation

Voltage regulation can be implemented as a standalone technology to protect equipment from voltage supply issues along with its other benefits. It can be connected to a high voltage or low voltage supply.

If you operate your own high voltage infrastructure, it can be integrated with an existing distribution transformer. Alternatively, your transformer can be replaced with a new, efficient distribution transformer with integrated voltage regulation. If you operate a low voltage supply only, it can still be implemented on your site.

Integrated into a battery energy storage solution with full Uninterruptible Power Supply (UPS) capabilities you can harness all the benefits of a consistent, uninterrupted power supply. This benefits your site by providing comprehensive power resilience and improved power quality. Due to its additional benefits of reducing electricity consumption and bills, it also improves the overall return on investment (ROI) of the battery energy storage solution.

Which sectors benefit most from voltage regulation?

Voltage regulation is best suited to environments where there is sensitive or critical electrical equipment, with long operating hours and a high level of electricity consumption. This means it performs well in sectors such as manufacturing, defence, retail and distribution, and healthcare.
