actions) and in the long term (for example functional
analysis).
The event recorder logs all selected binary input signals
connected to the Disturbance report function. Each
recording can contain up to 150 time-tagged events.
The event recorder information is available for the
disturbances locally in the IED.
The event recording information is an integrated part of
the disturbance record (Comtrade file).
Trip value recorder DRPRDRE
Information about the pre-fault and fault values for
currents and voltages are vital for the disturbance
evaluation.
The Trip value recorder calculates the values of all selected
analog input signals connected to the Disturbance report
function. The result is magnitude and phase angle before
and during the fault for each analog input signal.
The trip value recorder information is available for the
disturbances locally in the IED.
The trip value recorder information is an integrated part
of the disturbance record (Comtrade file).
Disturbance recorder DRPRDRE
The Disturbance recorder function supplies fast, complete
and reliable information about disturbances in the power
system. It facilitates understanding system behavior and
related primary and secondary equipment during and
after a disturbance. Recorded information is used for
different purposes in the short perspective (for example
corrective actions) and long perspective (for example
functional analysis).
The Disturbance recorder acquires sampled data from
selected analog- and binary signals connected to the
Disturbance report function (maximum 40 analog and 96
binary signals). The binary signals available are the same
as for the event recorder function.
The function is characterized by great flexibility and is not
dependent on the operation of protection functions. It can
record disturbances not detected by protection functions.
Up to three seconds of data before the trigger instant can
be saved in the disturbance file.
The disturbance recorder information for up to 100
disturbances are saved in the IED and the local HMI is used
to view the list of recordings.

Measured value expander block MVEXP
The current and voltage measurements functions
(CVMMXN, CMMXU, VMMXU and VNMMXU), current and
voltage sequence measurement functions (CMSQI and
VMSQI) and IEC 61850 generic communication I/O
functions (MVGGIO) are provided with measurement
supervision functionality. All measured values can be
supervised with four settable limits: low-low limit, low
limit, high limit and high-high limit. The measure value
expander block has been introduced to enable translating
the integer output signal from the measuring functions to
5 binary signals: below low-low limit, below low limit,
M12128-3 v6 normal, above high-high limit or above high limit. The
output signals can be used as conditions in the
configurable logic or for alarming purpose.
Station battery supervision SPVNZBAT
The station battery supervision function SPVNZBAT is
used for monitoring battery terminal voltage.
SPVNZBAT activates the start and alarm outputs when the
battery terminal voltage exceeds the set upper limit or
drops below the set lower limit. A time delay for the
overvoltage and undervoltage alarms can be set according
to definite time characteristics.
In the definite time (DT) mode, SPVNZBAT operates after a
predefined operate time and resets when the battery
M12156-3 v8
undervoltage or overvoltage condition disappears.
Insulation gas monitoring function SSIMG
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
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
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
