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