Smart scale energy solutions for electrical systems

Motor efficiency

When looking into the total life cycle costs of an electrical motor, energy costs are the biggest part. Therefore, investments in energy efficient motors or frequency inverters have a very fast payback. To quantify the real electricity consumption and savings of a motor exchange, real-time consumption data is relevant.

Electrical efficiency

Using electrical efficiency helps to identify saving potential. The electrical efficiency is the relation between useful power output and total power input. Besides the energetically reasons electrical efficiency helps to:

• Evaluate status and remaining lifetime

• Find out the ideal point of operation

• Avoid damages by constant monitoring

• Oversized pumps installed

• Eliminate bypass flows for control

• Install high efficiency motors

• Split volume flow to several pumps as a reaction of changing demands

System and phase load

Adaptations/enhancements of production facilities are often required. Therefore additional single phase consumers are often installed which leads to different loads of the phases. To identify/compensate asymmetrically phase load it is mandatory to monitor the electrical network which helps to:

• Evaluate/run the electrical system with a symmetrical phase load

• Indicate asymmetrical loads

• Decide where/if additional electrical components could be installed

• Avoid system problems/unscheduled downtime

Measuring and collecting is key

To identify and allocate the most electricity consuming assets and processes, measuring and collecting data are essential to have a base for further improvements.
Define the right KPIs which help you to evaluate:

• Motor efficiency

• Electrical efficiency

• System and phase load

• Real power compensation
