Input impedance
1-1-3
The apparent resistance of the mains supply R
drop of 6% at the maximum power load of 9 kVA.
For a nominal supply voltage of 380 V, the line resistance R
Ω
R
< 1
L(380)
For other supply voltages, calculate the equivalent permissable resistance value in ohms as follows:
R
= RL(380) x (U/380)
L(U)
Where:
U = local input voltage
R
= total apparent resistance (two–wire) of the supply at the local voltage (U).
L(U)
R
= total apparent resistance (two–wire) of the supply at 380 V.
L(380)
Thus, as R
must be less than 1
L(380)
