EEPROM—IRIG-B
EEPROM
Abbreviation for Electrically Erasable Programmable Read-Only Memory. Non-
volatile memory where device settings, event reports, SER records, and other
nonvolatile data are stored.
Event History
A quick look at recent device activity that includes a standard report header;
event number, date, time, and type; maximum fault phase current; and targets.
Event Report
A text-based collection of data stored by the device in response to a triggering
condition, such as a fault or command. The data show device measurements
before and after the trigger, in addition to the states of protection elements, device
inputs, and device outputs each processing interval. After an electrical system
fault, use event reports to analyze device and system performance.
Event Summary
A shortened version of stored event reports. An event summary includes items
such as event date and time, event type, fault voltages, currents, etc. The device
sends an event report summary (if auto messaging is enabled) to the device serial
port a few seconds after an event.
Fast Hybrid Control
Output
A control output similar to, but faster than, the hybrid control output. The fast
hybrid output uses an insulated gate bipolar junction transistor (IGBT) to
interrupt (break) high inductive dc currents and to very rapidly make and hold the
current until a metallic contact operates, at which time the IGBT turns off and the
metallic contact holds the current. Unlike the hybrid control output, this output is
not polarity sensitive; reversed polarity causes no misoperations.
Fast Meter, Fast Operate
Binary serial port commands that the device recognizes at the device front-and
rear-panel EIA-232 serial ports. These commands and the responses from the
device make device data collection by a communications processor faster and
more efficient than transfer of the same data through use of formatted ASCII text
commands and responses.
FID
Device firmware identification string. Lists the device model, firmware version
and date code, and other information that uniquely identifies the firmware
installed in a particular device.
Firmware
The nonvolatile program stored in the device that defines device operation.
Flash
A type of nonvolatile device memory used for storing large blocks of nonvolatile
data, such as load profile records.
Fundamental Frequency
The component of the measured electrical signal for which frequency is equal to
the normal electrical system frequency, usually 50 or 60 Hz. Generally used to
differentiate between the normal system frequency and any harmonic frequencies
present.
Fundamental Meter
Type of meter data presented by the SEL-2414 that includes the present values
measured at the device ac inputs. The word “Fundamental” is used to indicate
that the values are Fundamental Frequency values and do not include harmonics.
GOOSE
IEC 61850 Generic Object Oriented Substation Event. GOOSE objects can
quickly and conveniently transfer status, controls, and measured values among
peers on an IEC 61850 network.
IEC 61850
Internationally standardized method of communications and integration
conceived with the goal of supporting systems of multivendor IEDs networked
together to perform protection, monitoring, automation, metering, and control.
IRIG-B
A time code input that the device can use to set the internal device clock.
