(a)
In the software the power consumption data of both meters is added so you do NOT have
to set which meter covers which power consumption.
Exceptional cases. You can also use a second power meter if:
- The power range of one meter is insufficient.
- The power meter cannot easily be installed in the electrical cabinet.
- 230V and 400V three-phase grids are combined (very uncommon), because of
technical limitations of power meters.
Examples in case of normal kWh rate power supply
1 power meter is sufficient.
