0.Project Background:

One of our party A customers in KSA want a entire Online Energy Monitoring Solution (mainly of electricity) for their factory machines. Their basic

requests are "remote meter reading", "auto-generated daily&monthly&yearly energy consumption report for every machines and factory's overall power

consumption". In other words, they want to realize a digitalization of energy monitoring for their all factory machines so that they could set up energy

saving plan accordingly.

1.Factory Overview:

(1) The factory could be devided into 3 Areas for power consumption monitoring.(2) Area 1 was Main Power Distribution Room. Only 1 main incoming circuit 3-phase here need to be monitored. Circuit's rated current is 2500A

AC and its rated voltage is 3x400Vac L-L&3x230Vac L-N. Meanwhile, the circuit was carried by busbar with the size of 110mm*50mm (Cross

Section).

(3) Area 2 was 1st workshop with 12 machines 3-phase needed to be monitored. Each machine was powered by 1 circuit 3-phase. Circuit's rated

current is 400A AC and its rated voltage is 3x400Vac L-L&3x230Vac L-N. Meanwhile, the circuit was carried by cable with the size of 30mm

(diameter).

For Area 2 machines' distribution, each machine was far from each other, thus when we install the energy meters, all the energy meters will be

of separate installation and were also far from each other.

(4) Area 3 was 2nd work shop with 18 machines 3-phase needed to be monitored. Each machine was powered by 1 circuit 3-phase. Circuit's rated

current is 200A AC and its rated voltage is 3x400Vac L-L&3x230Vac L-N. Meanwhile, the circuit was carried by cable with the size of 20mm

(diameter).

For Area 3 machines' distribution, each machine was close to each other. So all the energy meters could be of centralized installation in a DB

cabinet.

(5) Both 3 areas are covered by stable 4G signal. Meanwhile, WiFi or Ethernet communication was not available for these areas.
