currents, is used to exactly calculate the fault position.
The fault can be recalculated with new source data at
the actual fault to further increase the accuracy.
Especially on heavily loaded long lines, where the source
voltage angles can be up to 35-40 degrees apart, the
accuracy can be still maintained with the advanced
compensation included in fault locator.
Event counter with limit supervison L4UFCNT
The 30 limit counter L4UFCNT provides a settable
counter with four independent limits where the number
of positive and/or negative flanks on the input signal
are counted against the setting values for limits. The
output for each limit is activated when the counted
value reaches that limit.
Overflow indication is included for each up-counter.
Running hour-meter TEILGAPC
The Running hour-meter (TEILGAPC) function is a
function that accumulates the elapsed time when a
given binary signal has been high.
The main features of TEILGAPC are:
• Applicable to very long time accumulation (≤ 99999.9
hours)
• Supervision of limit transgression conditions and
rollover/overflow
• Possibility to define a warning and alarm with the
resolution of 0.1 hours
• Retain any saved accumulation value at a restart
• Possibilities for blocking and reset
• Possibility for manual addition of accumulated time
• Reporting of the accumulated time

Pulse-counter logic PCFCNT
Pulse-counter logic (PCFCNT) 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
binary input module and then read by the PCFCNT
function. A scaled service value is available over the
station bus. The special Binary input module with
enhanced pulse counting capabilities must be ordered
to achieve this functionality.
Function for energy calculation and demand
handling (ETPMMTR)
Measurements function block (CVMMXN) can be used to
measure active as well as reactive power values.
Function for energy calculation and demand handling
(ETPMMTR) uses measured active and reactive power as

input and calculates the accumulated active and reactive
energy pulses, in forward and reverse direction. Energy
values can be read or generated as pulses. Maximum
demand power values are also calculated by the
function. This function includes zero point clamping to
remove noise from the input signal. As output of this
function: periodic energy calculations, integration of
energy values, calculation of energy pulses, alarm
signals for limit violation of energy values and maximum
power demand, can be found.
The values of active and reactive energies are calculated
from the input power values by integrating them over a
tEnergy . The integration of active and
selected time
reactive energy values will happen in both forward and
reverse directions. These energy values are available as
output signals and also as pulse outputs. Integration of
energy values can be controlled by inputs (STARTACC
EnaAcc setting and it can be reset to
and STOPACC) and
initial values with RSTACC input.
The maximum demand for active and reactive powers
are calculated for the set time interval
these values are updated every minute through output
channels. The active and reactive maximum power
demand values are calculated for both forward and
reverse direction and these values can be reset with
RSTDMD input.
