A large commercial building
Emma works at a large company and is responsible for everything related to energy. To gain maximum insight into the energy flows within the building, she wants to equip all major circuits and sub-distributions with kWh meters. The building has three floors, each with its own meter. In addition, she wants to monitor the production of the solar panel system, the consumption of the EV charging area, and various other small and large loads. In total, this amounts to 12 sub-meters.
The main connection of 250A is not equipped with a smart meter with a P1 port. Therefore, an indirect kWh meter is used in combination with 250A current transformers to read the data. To monitor the total gas and water consumption, two pulse sensors are used, which are installed on the meters.

Emma has a direct 3-phase kWh meter installed on all 12 circuits she wants to monitor. For the 250A main connection, an indirect kWh meter is used in combination with three current transformers. All kWh meters are interconnected and connected to the USB port of the CEMM 3.0 via an RS485 converter. The pulse sensors for gas and water are connected to ports 1 and 2.
