Compared to a four-conductor system, the use of symmetrical shielded cable reduces
electromagnetic emission of the whole converter system as well as generator bearing
currents and wear.
The generator cable and its PE pigtail (twisted screen) should be kept as short as possible
in order to reduce electromagnetic emission as well as capacitive current.
