frequency is specified in Frequency sub-menu. Other sub-menus menus under Measurement menu are mainly for monitoring
purposes.

TRANSFORMERS

Figure 3.43

Voltage transformer ratio is set in Transformers sub-menu

Among ratio settings the nominal values are determined in Transformers menu as well. Sometimes it is possible that due wiring the
polarity has to be changed because of mistake or other similar reason. It is possible to individually invert polarity of each phase
voltage. Transformers menu also displays more information like scaling factors for VTs and per unit values.

FREQUENCY

Figure 3.44

Frequency settings menu

•

Sampling mode is fixed as standard and System nominal frequency should be set to desired level. In case the Sampling mode is
set as tracking the IED will use measured frequency value as system nominal frequency.
