Smart Electric Meters - Energy Monitoring

 

Energy Monitoring with smart electric meters is the first step in understanding where to save energy, reduce costs and reduce carbon emissions. Learning which appliances are taking the most power can lead to 20 to 25% energy savings in your electricity bills. Smart electric meters will help you save energy, reduce electricity costs and reduce carbon emissions. Energy Monitoring allows you to monitor power at various points in the organisation and gives you much finer information about energy usage. Sub-meters help to pin-point wasted electricity.

 

The PowerEYE 500 is a smart electric meter with a difference. As well as having a large display showing current and power consumption in 3-phase circuits, it transmits readings every night using a GSM link to a web site. The half-hourly energy monitoring data can be viewed in graphical form using any PC with an Internet connection.

 

This smart electric meter is easily deployed to different distribution boards around the company. It connects quickly using split core current clamps. It makes energy monitoring a very simple task.

Voltage Reduction

 

Most lighting is designed to work at 230V. In the UK the mains voltage is usually around 240V and can often be 245V or even 250V either when demand is low (say overnight) or if close to a sub-station.

 

Reducing the voltage to lighting down to 220V can save energy without noticeably reducing light levels. A 10% reduction in voltage can result in 15 to 20% reduction in current due to the non-linear behaviour of lighting. This will often give 20 to 30% reduction in power.

 

Voltage reduction to lighting has a number of other benefits. The life of the bulb can be increased significantly leading to a lot lower maintenance costs. The wasted electricity in lighting from being run at a higher voltage is dissipated as heat. This results in undue demand from air-conditioning leading to additional wasted electricity. Reducing the current in lighting circuits will reduce copper losses in electrical wiring as well.
