In the definite time (DT) mode, SPVNZBAT operates after a
predefined operate time and resets when the battery
undervoltage or overvoltage condition disappears.
Insulation gas monitoring function SSIMG
GUID-0692CD0D-F33E-4370-AC91-B216CAAAFC28 v3
Insulation gas monitoring function SSIMG (63) is used for
monitoring the circuit breaker condition. Binary
information based on the gas pressure in the circuit
breaker is used as input signals to the function. In
addition, the function generates alarms based on received
information.
Insulation liquid monitoring function SSIML
GUID-3B1A665F-60A5-4343-85F4-AD9C066CBE8D v3
Insulation liquid monitoring function SSIML (71) is used
for monitoring the circuit breaker condition. Binary
information based on the oil level in the circuit breaker is
used as input signals to the function. In addition, the
function generates alarms based on received information.
Circuit breaker monitoring SSCBR
GUID-E1FD74C3-B9B6-4E11-AA1B-7E7F822FB4DD v7
The circuit breaker condition monitoring function SSCBR
is used to monitor different parameters of the circuit
breaker. The breaker requires maintenance when the
number of operations has reached a predefined value. For
proper functioning of the circuit breaker, it is essential to
monitor the circuit breaker operation, spring charge
indication, breaker wear, travel time, number of operation
cycles and accumulated energy. The energy is calculated
from the measured input currents as a sum of I
^
2 t values.
Alarms are generated when the calculated values exceed
the threshold settings.
The function contains a blocking functionality. It is
possible to block the function outputs, if desired.
11. Metering
Pulse counter logic PCGGIO
M13394-3 v6
Pulse counter (PCGGIO) function counts externally
generated binary pulses, for instance pulses coming from
an external energy meter, for calculation of energy
consumption values. The pulses are captured by the BIO
(binary input/output) module and then read by the
PCGGIO function. A scaled service value is available over
the station bus.
Function for energy calculation and demand handling
ETPMMTR
SEMOD153641-8 v5
Outputs from the Measurements (CVMMXN) function can
be used to calculate energy consumption. Active as well as
reactive values are calculated in import and export
direction. Values can be read or generated as pulses.
Maximum demand power values are also calculated by the
function.
12. Human Machine interface
Local HMI
AMU0600442 v7
GUID-DA949D6F-070D-4D84-82AC-6791EF64F84F V1 EN-US
Figure 2. Local human-machine interface
The LHMI of the IED contains the following elements:
• Display (LCD)
• Buttons
• LED indicators
• Communication port
The LHMI is used for setting, monitoring and controlling .
GUID-CABB3689-DEA5-4611-A492-13B3D6632846 v3
The Local human machine interface, LHMI includes a
graphical monochrome LCD with a resolution of 320x240
pixels. The character size may vary depending on selected
language. The amount of characters and rows fitting the
view depends on the character size and the view that is
shown.
The LHMI can be detached from the main unit. The
detached LHMI can be wall mounted up to a distance of
five meters from the main unit. The units are connected
with the Ethernet cable included in the delivery.
The LHMI is simple and easy to understand. The whole
front plate is divided into zones, each with a well-defined
functionality:
