DIGITAL FILTER PROGRAMMING EXAMPLES
PROGRAMMING WM30-96
11
Example 1
How to stabilize the value of the VL-N variable displayed on the display, fluctuating from 222V and 228V.
The parameters of the digital filter have to be programmed as follows:
FILTER S: the variable has fluctuations within the mean value whose
amplitude is equal to ±0,75% of the full scale rated value of the variable
itself (obtained by the following calculation: (228-222)/ 2= ±3V, then
±3*100/400V= ±0,75% where 400V is the phase-neutral rated value of an
AV5 input). The “range” parameter, representing the action range of the
digital filter, is to be programmed to a value which must be slightly higher than the percentage amplitude of the fluctuation: ex. 1.0%.
FILTER CO: if the new value measured by the instrument is within the
action range of the filter, the new displayed value is obtained by adding
algebrically the previous value to the variation divided by the filtering
coefficient. As a consequence, a value higher than this coefficient implies
a longer settling time and therefore a better stability. You generally obtain
the best result by setting the filtering coefficient to a value equal to at
least 10 times the range parameter value.
In the following example: 1,0*10=10, the stability of the filtering coefficient can be improved by increasing the filtering coefficient, the admitted
values are included within 1 and 255.
Example 2
How to stabilize the value of the displayed System Active Power
(W∑), fluctuating between 300kW and 320kW (the load is connected
to the instrument by means of a 300/5A CT and a direct measure of
the voltage).
The parameters of the digital filter must be programmed as follows:
FILTER S: the variable has fluctuations within the mean value whose
amplitude is equal to ±2,78% of the full scale rated value of this variable.
This value is obtained by the following calculation: (320-300)/ 2= ±10kW,
then ±10*100/360kW= ±2,78%, where 360kW is the rated value of the
System Active Power of an AV5 input, at the above mentioned CT and VT
ratios and obtained by means of the following formula: (320-300)/ 2=
±10kW, then ±10*100/360kW= ±2,78%, where 360kW is the rated value
of the System Active Power of an AV5 input
at the above mentioned CT and VT ratios and obtained by means of the
following formula: “VLN * VT * IN * CT * 3” where VLN = rated input voltage (400V for the AV5 input), VT= primary/secondary ratio of the voltage
transformer being used, IN = rated current (5A for the AV5 type input), CT
= primary/secondary ratio of the voltage transformer being used (in this
example “400*1*5*60*3=360kW).
The RANGE parameter, representing the digital filtering coefficient action
range, is to be programmed to a value which must be slightly higher than
the percentage of the fluctuation: ex. 3.0%.
FILTER CO: if the new value acquired by the instrument is within the filtering
action range, the new displayed value is obtained by adding algebrically the previous value to the variation divided by the filtering coefficient. As a consequence,
a value higher than this coefficient implies an higher settling time and therefore a
better stability. Generally speaking the best result is obtained setting the filtering
coefficient to a value equal to at least 10 times the value of the range parameters.
In the example: 3.0*10=30. In order to improve the stability you can increase the
filtering coefficient, the admitted values are included within 1 and 255.
Example 3.
It’s necessary to stabilize the value of the displayed variable AL 1
(phase current 1), fluctuating within 470V and 486V.
To be able to manage the alarm function and following activation and
deactivation of the relay, this value is not to be subject to continuous
fluctuations. In this example we have considered using a 500/5A CT. The
paramters of the digital filter is to be programmed as follows:
FILTER S: the variable has fluctuations within the mean value whose
amplitude is equal to ±1,60% of the full scale rated value of this variable
(obtained by means of the calculation: (486-470)/ 2= ±8A, then
±8*100/500V= ±1,60% where 500A is the value referred to the primary of
the transformer being used). The “range” parameter, which represents the
action range of the digital filter, is to be programmed to a value slightly
higher than the pourcentage amplitude of the fluctuation: for example
2.0%.
FILTER CO: if the new value acquired by the instrument is within the filtering action range, the new displayed value is calculated algebrically
adding to the previous value the variation divided by the filtering coefficient. As a consequence, a higher value of this coefficient implies a higher settling time and therefore a better stability. Generally speaking, the
best result is obtained setting the filtering coefficient at a value equal to
at least 10 times the value of the range parameter. In the example:
2.0*10=20. To improve the stability you can increase the filtering coefficient, the admitted values are within 1 and 255.

PROGRAMMING EXAMPLES OF THE ANALOGUE OUTPUTS
PROGRAMMING WM30-96
12
Power retransmission by means of a 0-20mA analog output.
It’s necessary to measure a consumed power up to 100kW and retransmit this value by means of a signal from 4 to 20 mA: the module to be
used is AO2050 (2x from 0 to 20mA), the instrument is to be programmed
as follows:
VARIABLE: W∑ (system active power).
MIN OUT: 20.0% means 4 mA the calculation to be carried out is the fol-
lowing: (100*minimum output) / fullscale output =100*4mA/ 20mA=20%.
MAX OUT: 100.0% means 20mA, the calculation to be carried out is:
(100*maximum output) / fullscale output = 100*20mA/20mA= 100.
MIN INPUT: 0,0k; the multiple k,M,G can be selected on the instrument
according to the chosen VT and CT values.
MAX INPUT: 100.0k; the k, M, G multiples can be selected on the instrument according to the selected VT and CT values.
Retransmission of the POWER FACTOR (PF) by means of the
0-20mA analog output.
It’s necessary to retransmit the whole range of the admitted values for the
PF with a signal from 0 to 20mA. Particular attention must be paid to the
value of the PF variable which may vary from C0,001 and L0,000 (for each
phase): these values will be retransmitted and will then correspond to 0
and 20 mA. When the PF will have a value equal to 1, being in the middle between C0,001 and L0,000, the value of the output will correspond
to the middle of the scale, that is 10mA. As a consequence, the instrument will have to be programmed as follows:
VARIABLE: PF L1 (or L2 or L3 or PF∑).
MIN OUT: 0,0%.
MAX OUT: 100,0%.
MIN INPUT: C0,001 (the C symbol shows a CAPACITIVE value).
MAX INPUT: L0,001 (the L symbol shows an INDUCTIVE value). L0,001
has been chosen as minimum value to be set in order to avoid any undesirable swifting of the repeated outputs.
