Voltage

Voltage is displayed as three-phase r.m.s measurement of the phase-neutral and/or phase-phase voltages.

Package

SC

utilizes single-phase r.m.s. measurement of the synchronizing voltage V

L1-L2

.

This device can be ordered with the following measuring voltage input ranges (rated voltages). Please indi-
cate the measuring voltage input required when ordering (refer to Technical Data on page 48):

•

66 V/115 V ....................[1]

•

230 V/400 V ....................[4]

•

400 V/690 V ....................[7]

Frequency

Frequency measurement is extracted from the digitally filtered measuring voltages. The frequency is meas-
ured three-phase if the measured voltage exceeds 15% of the nominal voltage. This ensures rapid and precise
measurement of the frequency. However the frequency is still measured correctly even if voltage is only ap-
plied to one phase.
