ABB drives display energy savings

London – Users of ABB industrial drives and ABB standard drives can now see exactly how much energy they are saving with a new application that displays the information on the drive’s screen. The drives’ built-in energy efficiency parameters work out energy savings of the application in kWh and MWh; the cost of the energy saved in a local currency; and the carbon dioxide emissions equivalent of the energy saved.

All these energy related measurements are displayed through the control panel’s alphanumeric display and can be accessed by pressing a combination of the soft keys.

The energy consumed when the fan or pump is used direct-on-line is compared with the energy used once the drive is installed and running. The drive then calculates energy savings in kWh or MWh with reference to this baseline and displays it in an easy to read way on its built-in screen.

Saved money is displayed in local currency after the user has set the local energy cost as a reference, while a CO₂ conversion factor (tn/MWh) is used to convert energy into CO₂ emissions.

All these measurements can help ensure that a plant or process is working to its optimum performance, while avoiding the extra cost of external energy measuring equipment.

The information can be used by plant engineers and energy managers to ensure that the application is attaining its optimum level, as well as by financial controllers and board level directors interested in keeping a closer control on the operational expenditure of a plant or process.
