OPERATING PRINCIPLES
2.1. PROTECTION FUNCTIONS
2.1.1. OVERCURRENT UNITS
SMOR system includes the following overcurrent units, all of which can be set and used independently:
•Phase overcurrent (for three phases):
Time delayed 51 PT (Instantaneous, definite or inverse time)
Instantaneous, High level 50 PH (Instantaneous or definite time delayed)
Instantaneous, Low level 50 PL (Instantaneous or definite time delayed)
•Ground overcurrent:
Time delayed 51 NT (Instantaneous, definite or inverse time)
Instantaneous, High level 50 NH (Instantaneous or definite time delayed)
Instantaneous, Low level 50 NL (Instantaneous or definite time delayed)
Any unit can be set to be directional or non-directional, independently.
•Negative sequence overcurrent:
Time delayed 46 PT (Instantaneous, definite or inverse time)
The timed units can be selected using Inverse, Very Inverse, Extremely Inverse curves, or definite time
characteristic. These inverse time curves are shown in Figures 2, 3 and 4 and follow the equation:
K
t=TD M
∝-1
in which:
t= Time in seconds
TD = Time Dial of the curve (0.05 for the lower curve of the family and 1 for the upper curve)
M= Multiples of the pickup value
K, αare coefficients which identify the selected curve and which correspond to the following table:
Curve Characteristic K α
αα
α
1 Inverse 0.13 0.02
2 Very inverse 16 1
3 Extremely inverse 96 2
2.1.2. DIRECTIONAL SUPERVISION SETTING
The SMOR system has three phase directional units and one ground directional unit. They are completely
independent on each other, being used to supervise (assuming they are adjusted to do so) the tripping of the
phase and ground overcurrent units, according to the direction of the detected fault (they do not affect the
trip of the negative sequence overcurrent unit). The directional supervision can be adjusted independently for
each of the overcurrent functions of the SMOR system, both for phases and ground.
The phase directional units are polarized by phase-to-phase voltages, while the ground directional unit is
polarized by zero sequence voltage. The characteristic angle of the unit can be independently set for the
phase and ground units.

GEK-105593C

To protect against loss of polarization voltage, the system includes adjustable fuse-failure logic. This logic
allows to either block the operation of the units or to convert the directional units into non-directional. The
selection is done through a setting. The fuse failure function operates on two different conditions (OR logic):
- Operation of undervoltage detectors (adjusted at 3.5 volts)
- Activation of a digital input connected to the voltage MCB.
2.1.3. VOLTAGE UNITS
•Phase over and under voltage:
•Under voltage: 27P
•Over voltage: 59P
The three-phase under and overvoltage units operate under conditions of under or over voltage (depending
on the unit) in any of the three phases. Both units are adjusted and operate on phase-to-phase voltage
values, calculated from the phase-to-ground voltages applied to the unit.
• Ground overvoltage:
•High Setting: 59 NH
•Low Setting: 59 NL
There are two ground overvoltage units. The SMOR7000 model has a dedicated open-delta input. In all
other models the voltage is calculated from the phase to ground inputs.
2.1.4. FREQUENCY UNITS
• Underfrequency : 81U
• Overfrequency: 81O
The under and over frequency units are measured on one phase (phase B).

2.2. MONITORING AND REGISTERING FUNCTIONS.
2.2.1. MEASUREMENT
The SMOR system offers the following metering capabilities:
- Three-phase and ground current.
- Negative sequence current.
- Phase-to-phase voltages.
- Active and reactive power.
- Power factor.
- Frequency.
The RMS value for currents and voltages is calculated for each phase, and the phase-to-phase voltages are
calculated from the phase to ground voltages. The active and reactive power are also computed on these
values. The active and reactive power, and the power factor are only shown as three-phase values.
These measurements can be accessed locally on the liquid crystal display (LCD) on the front of the relay, or
via the GE-LOCAL communication software.
The SMOR unit has a demand register, as well as a maximeter register for current and active power. For the
demand register, the maximum and average RMS current are calculated over a selected period of 15, 30 or
60 minutes corresponding to the last 24, 48 or 96 hours respectively. The maximeter register computes the
maximum value for current and power for periods which are the same as those selected for the demand
register.
2.2.2. ASSOCIATED BREAKER STATUS
SMOR system monitors breaker status associated to the unit with a digital input (52/b). The breaker status
can be accessed using the local MMI or the communication software, which shows the breaker status in real
time through a visual simulation of the line.
2.2.3. LED INDICATORS.
An internal states matrix stores the digital information for all the units (inputs, pick-ups, alarms, etc). The
digital signals on this matrix are grouped in groups of 16 signals; there are 10 groups; It is a 10 x 16 matrix;
the final group corresponds to the 16 AND gates definable using the programmable logic of GE-INTRO
software.
The SMOR unit has a total of 17 LED indicators, one fixed bicolor assigned to the critical alarm function of
the unit and 16 red LED indicators, arranged in two columns of 8 LEDs. They can be configured using the
GE-INTRO configuration software to any of the user definable alarms (32 protection alarms and 16
communication alarms) assigned from among the protection and communication states. To define each
alarm, the user can use 16 inputs OR gates. All the inputs to an OR gate must belong to the same group in
the states matrix. Similarly, each LED can be configured to have memory in the absence of auxiliary power
supply (the status of the LED with memory is registered on the EEPROM memory). They can also be
configured to blink when turned on.
There is a test option for the LEDs, lighting them all up when the TARGET RESET button is pressed. When
this button is held down the LED indicators are reset.
The SMOR units are supplied from the manufacturer with the following default configuration of the LEDs:

5 Timed Overcurrent trip 13 Circuit Breaker Open
6 Instantaneous Overcurrent trip 14 Coil supervision alarm
7 Negative sequence trip 15 Unit alarm
8 Voltage trip (27/59/59N) 16 Remote communication mode
2.2.4. SUPERVISION OF TRIP AND CLOSING CIRCUITS
On the optional expansion board there are two complete supervision circuits for the trip and/or closing coil of
the breaker (one input for each coil). These supervision inputs monitor both the battery voltage and the
continuity of the tripping or closing circuits, monitoring the flow of a small current injected into the circuit.
The unit independently identifies in the event recorder and states matrix the continuity of each coil ("coil
continuity alarm") and the loss of voltage to command the breaker ("coil DC supply alarm.")
Circuit supervision is carried out on a permanent basis, regardless of whether the breaker is in the open or
closed status, since the supervision circuit is connected both to contact 52/a and 52/b of the breaker. For the
supervision to be carried out correctly, the supervision circuits must be connected to the tripping or closing
coils as shown in the following diagrams:

CLOSE CIRCUIT SUPERVISION
2.2.5. BREAKER HEALTH MONITORING
To supervise the breaker health, SMOR system calculates and stores, for each operation, the accumulated
values for the square of the current multiplied by the opening time of the breaker (ΣI2t) on each of the three
phases. If the nominal current is not exceeded, as is the case for a manual opening command with no fault
current, the relay uses the nominal current value instead of the measured value.
The value I2t is accumulated and stored independently for each phase. These values can be accessed
either by local MMI or by GE-LOCAL communication software.
The function has an "Integration Time Selector" setting which can be used to assign a fixed opening time
(given by another "Integration Time" setting). Otherwise it allows the unit to measure this time from the
moment the opening command is given until the moment when the breaker opens.
The "Accumulative Current Limit" setting establishes a threshold for the breaker's interruption capability (it is
advisable to set this to the limit supplied by the manufacturer). When this threshold is passed on any of the
three phases, the system gives an alarm. In addition, the system incorporates a counter for the number of
opening operations carried out.
The purpose of this function is to allow maintenance to be carried out in a more accurate method than using
fixed time periods. Once this maintenance operation has been carried out, the values for both the I2t and
number of opening operations, can be reset to zero.
In order to be able to take into account the history of the breaker, in the case where the breakers were
already in use before the installation of the relay, the system allows to set an initial value for the ΣI2tandthe
number of opening operations carried out. Similarly, these values can be adjusted to a given value in order
to take into account the operations carried out during the protection testing.

2.2.6. PHASE ROTATION SEQUENCE SELECTION
The SMOR system works correctly with any phase sequence selection ABC or CBA without the need to
change the wiring of the external transformers, since there is a setting which allows the selection of the
phase rotation sequence.
2.2.7. SELF-CHECKING FUNCTIONS.
Thanks to its digital technology, the SMOR system incorporates self-checking functions which guarantee the
correct performance of the unit and will block the operation in case of internal errors.
These self monitoring checks are carried out both when the unit is started up and during normal operation.
The checks are carried out on the internal power supply, program memory (ROM), working memory (RAM),
oscillographic memory (RAM) and settings and calibration memory (EEPROM).
In addition there is a hardware test for the LED indicators, which light them all up when the button TARGET
RESET is pressed. If the button is kept pressed down for more than one second the memory for all the
indicators is reset.

2.3. ANALYSIS FUNCTIONS.
The SMOR system includes an event recorder and an oscillographic recorder with 1 msec. time tag
resolution. So as not to lose the date and time setting or the oscillographic recorder information, the unit uses
a capacitor as backup for the internal clock and register memory. This allows the information to be kept for at
least 24 hours from the moment the power supply is lost.
2.3.1. EVENT RECORDER
The SMOR system keeps a record of the last 144 events and stores the following information: date and time
(1 msec. resolution), the type of event, current and voltages measured at the time the event occurred, and
the internal states matrix of the unit.
This event recorder is stored in a non-volatile memory and can be maintained indefinitely, even with no
power supply.
The relay generates an event when any of the following signals changes its status:
