Voltage Connection
Address
97&RQQHFWLRQ
specifies how the voltage transformers are connect-
ed. When the voltage transformers are connected in a wye configuration, address
is set at
9DQ
,
9EF
,
9FQ
. When the voltage transformers are connected as shown
in Figure A-40 of Appendix Section A.4, address should be set at
9DE
,
9EF
,
9*QG
. The
latter setting is also selected when only two phase-to-phase voltage transformers are
utilized or when only the displaced voltage (zero sequence voltage) is connected to
the device.
Nominal Frequency
Address
5DWHG)UHTXHQF\
corresponds to the frequency at which the protect-
ed equipment operate. The setting is dependent on the model number of the relay pur-
chased, and must be in accordance with the nominal frequency of the power system.
Units of Length
Address
'LVWDQFH8QLW
corresponds to the units of length (km or miles) ap-
plicable to fault locating. If a fault locator is not included with the device, or if the fault
locating function is disabled, this setting has no effect on operation of the device.
Changing the length unit will not result in an automatic conversion between the sys-
tems. Such conversions must be entered at the appropriate addresses.
6.1.1.1
Settings
In the list below, the setting ranges and default setting values for the pickup currents
are for a device with a nominal current rating I
N
= 5 A. For a nominal current rating I
N
= 1 A, divide the Setting Options values and Default Setting values by 5. Consider the
current transformer ratios when setting the device with primary values.
