Why Manage Voltage?

• Reduce electricity

consumption

• Save money
• Save the planet
• Protect appliances
• Monitor electricity

use

Slide 2

Distribution Networks

Voltage supplied to customers varies over time in response to changing loads. Network operators must ensure that supplies are kept within the legislated voltage range.

380V ± 6% 220V ± 6%

Voltage Variance

• Electricity supplies are not normally at the nominal voltage
• Higher voltage produces higher consumption and reduced

appliance life

• Voltage below the minimum can cause brownout and

damage to appliances

Slide 4

About Supply Voltages

14/03/2018 Slide 5

Supply voltages are typically at the upper end of the range to allow for increased loads. Supply voltage over 24 hours

What Do Our Products Do?

• BlueGreen products maintain a constant

voltage in the home and workplace

– reducing consumption and bills – protecting appliances from damaging voltages – extending appliance life – providing consumption and savings data

Slide 7

• App is available on iOS

and Android

• Reports live and historic

data

• Next: Aggregated data

for landlords and commercial applications

The BlueGreen drives the transformer primary with a signal whose magnitude is continuously adjusted to create the required waveform on the secondary. This induced secondary voltage is added to or subtracted from the supply to create the desired load voltage.

Liverpool John Moores University Testing

Slide 10

• Tests sought to establish benefits of

BlueGreen technology

• Testing completed in February 2018

Description of Tests

Slide 11

• Each appliance was operated at average UK

voltage and then at regulated voltage

• Aggregated load was tested over a 24-hour period
