Measuring the ship source impedance
Select a power outlet from the ship 24 V DC or 12 V DC system, and measure the source impedance
of the ship installation as described below.
1.
Measure the voltage without load (R.var disconnected).
2.
Set the current to e.g. 1 A by adjusting R.var.
3.
Measure the corresponding voltage change.
Example:
1 A and 50 mV. Source impedance: 50 mV/1 Amp = 50 m
