Phase synchronization in 3-phase system
The synchronization in a 3-phase coupler system is taken from the phase L1 and
neutral. In case of a delta supply without neutral connected, an artificial neutral
point is defined by a high impedance network. This artificial neutral is taken for the
phase synchronization.
For all couplings the generator calculates the correct phase angle for phase
triggering.
In case of too high phase shifting the user can connect a proper sync signal to the
SYNC IN plugs at the rear side of the compact NX generator
The tables below shows the correction angels considering the phase in a 3-phase system with synchronization
signal from L1-N lines. The generator firmware will automatically add the correction angle to the settled value.

Charging time for surge
The energy for charging the surge generator depends on the charging voltage of the internal capacitor of 11 uF
therefore the following minimum charging time is requested:
