8 APPLICATION EXAMPLES
Fig 8.1
WARNING
Never ever make this hook-up while
current is being generated. If you do,
you may be exposed to dangerously
high voltages.
8.4 Testing a direct acting
automatic recloser
Setting the currrent and testing the pick-up level is
done in the same way as when testing low voltage
circuit breakers, see section 8.1.
1]
Press
ESC
to obtain the maximum current
during a test for reclosers that change their
impedance.
At time tests INGVAR will generate current until:
the
OFF
button
is pressed
or
a preset maximum generation time is reached.
After the cycle is completed the following measure-
ments are stored and displayed:
A]
Number of operations (number of times the
current is interrupted).
B]
The total accumulated time taken by the re-
closing cycle (i.e. from the recloser’s first trip
to its last trip).
C]
The trip and reclosing times.
D]
The current at the first four trip operations.
The showed value is the average of the current at the
beginning and the end of the operation.
Time test
1]
Press the
APPL
button.
2]
Turn the
Select/set knob
until "NORMAL"
appears on the display.
3]
Use the
Current adjust knob
to set the cur-
rent.
4]
Press the
APPL
button.
5]
Turn the
Select/set knob
until "TEST RECLOS-
ER" appears on the display and then press
INGVAR will now work as a recloser test
equipment.
Note
Range for "A-METER 1" will automatically be
changed to "LOW".
The Hold-feature is not active in "TEST
RECLOSER".
6]
To get a limited-time measurement, activate
"
MAX TIME
" and set the desired maximum
generation time.
7]
Press
TIME
or
MOM
to start the test.
INGVAR now generates current continuously
while the direct acting automatic recloser
trips and closes alternately. For each time the
current is interrupted, the number of opera-
