rated conditions. This facility provides ease of interface with applications which use the
same post divider with mechanical counter or unchanged microcontroller software for
different current rated kWh meters.
For example, a meter manufacturer may wish to build meters for 3 system configurations
with rated current loading of 80A
RMS
, 60A
RMS
and 40A
RMS
. The rated line voltage is
230V
RMS
.
FOUT1 Frequency
Consider the case where FOUT1 is the output of the energy counting block. For each
of the three rated conditions, the input current sensing resistors are chosen to ensure that
16μA
RMS
flows into the current sensing pins.
Case 1
I
L
= 80A
RMS
1 pulse on FOUT1 = (80*230*3)/1160 = 47.6Ws
Case 2
I
L
= 60A
RMS
1 pulse on FOUT1 = (60*230*3)/1160 = 35.7Ws
Case 3
I
L
= 40A
RMS
1 pulse on FOUT1 = (40*230*3)/1160 = 23.8Ws
The amount of energy represented by one pulse for each of the three cases is different.
In addition to changing the current sensing resistor network, the energy counting block
must also be altered.
FOUT2 Frequency
Now consider the advantage of the user selectable frequency available on FOUT2. Again
the input current sensing resistors must be chosen to ensure that 16μA RMS flows into the
current sensing pins.
Case 1
I
L
= 80A
RMS
,
PGM1 = 0
PGM0 = 0
1 pulse on FOUT2 = (80*230*3)/5.11 = 10.8kWs
Case 2
I
L
= 60A
RMS
,
PGM1 = 0
PGM0 = 1
1 pulse on FOUT2 = (60*230*3)/3.83 = 10.8kWs
Case 3
I
L
= 40A
RMS
,
PGM1 = 1
PGM0 = 0
1 pulse on FOUT2 = (40*230*3)/2.55 = 10.8kWs
The only changes which now have to be implemented to interface the device to different
rated systems are: change the current sense resistors; and select the required PGM0 and
PGM1.
No change to the post divider or micro-controller software is required if the FOUT2 pin is
used as described.
TYPICAL APPLICATION
In the Application Circuit (Figure 1), the components required for a three phase power
metering application are shown.
Terminated current sensors (current transformers) are connected to the current sensor
inputs of the IL19006 through current setting resistors (R
8
..R
13
).
