[300 A]

This value specifies the mains rated current, which is used as a reference

figure for related functions.

1858 1Ph2W voltage

measuring

3 [Phase

phase]

The unit is configured for measuring phase-phase voltages if 1Ph 2W meas

uring is selected.

Phase – neutral The unit is configured for measuring phase-neutral voltages if 1Ph 2W meas

uring is selected.

Notes

For information on measuring principles refer to Ä Chapter 3.2.5.1 “Generator

Voltage” on page 47.

Never configure the busbar measurement for phase-neutral, if the other sys

tems like mains and generator are configured as 3Ph 3W or 3Ph 4W. The

phase angle for synchronization would be not correct.

If this parameter is configured to 1Ph 3W, the generator and mains rated vol

tages (parameters 1766 Ä p. 98 and 1768 Ä p. 98) must be entered as Line

Line (Delta) and the busbar 1 rated voltage (parameter 1781 Ä p. 98) must

be entered as Line-Neutral (WYE).
