Imax = Fuse size (in this case 50A)
Imonitored = Ics2 + Ics3 + Ics4
Imax = Fuse size (in this case 80A)
Imonitored = Measured current in fuse
by LI 2, through CT .
Imax = Fuse size (in this case 100A)
Imonitored = Measured current in fuse
by LI 1 through HAN
interface.
Incomming current/Main fuse
Note: Only CS loads in this circuit, no need for any LI or dedicated energymeter.
