AC output connection specification
Voltage PVS800-57B-1645kW-C: 380 V AC 3-phase +/- 10%
PVS800-57B-1732kW-C: 400 V AC 3-phase +/- 10%
Allowed electrical system
type
3-phase IT (ungrounded) system. Galvanic isolation for each inverter is
needed.
Transformer The transformer must be suitable for IGBT-based inverter use with high du/dt
values against the ground. Dedicated low-voltage winding is needed for each
inverter. Static screen between windings with proper dimensioning is
needed.
For details on selecting the transformer, refer to Selecting the transformer on
page 33.
Short-circuit withstand
strength (IEC 60439-1)
Maximum allowable prospective short-circuit current is 50 kA when protected
by fuses given in fuse tables.
When
temporary grounding for work is applied (one set of grounding cables
are connected to the connecting knobs of the AC and DC busbars and PE of
the inverter): the maximum allowable prospective short-circuit current is
decreased to 40 kA / 1 s. If the connected grounding cables and clamps are
not equivalent to the prospective short-circuit rating of the inverter, the total
rating will be lower.
Frequency 45 to 65 Hz withstand with normal dimensioning (grid-compliance may
require disconnection at smaller values.) Maximum rate of change 17%/s
Imbalance Max. ± 3% of nominal phase to phase AC line voltage
Voltage dips Max. 0%
