Setting the Relay
Identifier and System Parameter Settings
Identifier and System Parameter Settings
The following explanations are for relay settings (accessed under the
SET
command) that control general relay configuration.
Relay ID (RID) and Terminal ID (TID)
The SEL-587Z has two identifier labels: the Relay Identifier (RID) and the
Terminal Identifier (TID). The Relay Identifier typically is used to identify the
relay or the type of protection scheme. Typical Terminal Identifiers include an
abbreviation of the substation name and line terminal.
The relay tags each report (event report, meter report, etc.) with the Relay
Identifier and Terminal Identifier. This tagging helps you distinguish the
report as one generated for a specific breaker and substation.
RID and TID settings may include the following characters: 0–9, A–Z, -,
/, ., space.
CT Ratio (CTR)
Determine the CT ratio by dividing the nominal primary CT current by the
nominal secondary CT current. If, for example, the nominal primary CT
current is 2000 A and the nominal CT current is 5 A, the ratio is 2000/5 or
400. For this example, enter a value of 400.
System Frequency (NFREQ) and Phase Rotation (PHROT)
Use the relay settings NFREQ and PHROT to configure the SEL-587Z to your
specific system.
Set NFREQ equal to your nominal power system frequency, either 50 Hz or
60 Hz.
Set PHROT equal to your power system phase rotation, either ABC or ACB.
DATE_F
Set the date format with this command. The format can be either mm/dd/yy or
yy/mm/dd. Set DATE_F equal to MDY for the former and equal to YMD for
the latter.
