3. Device description
3.1 Area of application
For humans, electric current is not immediately visible. Power quality analysers for mon-
itoring electrical parameters are used wherever energy consumption, power demand
measurements or the quality of the supply voltage are to be made visible.
The PEM735 is suitable for monitoring
 
Power generation systems (PV systems, CHPs, hydro power and wind power
plants)
 
Energy-intensive equipment and parts of installation
 
Sensitive equipment
