CPC 100
V 3.20
Quick - 1
Quick is the most basic mode to operate all of the
CPC 100
outputs in a manual-like mode with
front panel control.
Range
The output range combo box provides a list of available output ranges including either
CB2:
,
CU20:
or
CU1:
output ranges if the respective external booster was selected at the
Options
tab
Device Setup
or on the
Settings
page.
The
Settings
page allows setting the test cards individually. At the
Device Setup
tab in the
Options
view (see page Introduction-5), the same properties can be set for all test cards of a
test procedure. As a rule, do not use the
Settings
page but the
Device Setup
tab in the
Options
view to set the test cards. Making different settings for the test cards is rarely a good idea. Set
the test cards individually using the
Settings
page only in well-founded cases.
If a test card contains results, the settings cannot be changed. When a file containing results is
loaded, the
Settings
page can be used to view the settings of the test procedure.
If the output quantities of the selected output can be measured, the combo boxes “1
st
measured
quantity” and “2
nd
measured quantity” provide
I Out
and / or
V Out
for selection.
I Out sel
and
V Out sel
designate the frequency-selective measurement to filter out
interferences as they usually occur in substations. The measured input is filtered according to
the set output frequency.

Pressing the
Settings
menu key opens the
Settings
page. The
Settings
page
with the exception of the
TRRatio
test card looks as shown below.
After having set all necessary parameters, press the I/O (test start/stop) push
button. The
Quick
test card enters the “on” state, the set power output value is
switched to the
CPC 100
’s outputs, the measuring continues.
Pressing the
Quick
test card menu key
Keep Results
saves the currently
measured values and “freezes” their display in the measurement table. Both the
“measuring” and the “on” state remain active, the measurement continues in a
new line of the measurement table.
DANGER
Death or severe injury caused by high voltage or current
Together with the test object’s capacity, the leakage inductance of the
CPC 100
’s
internal output transformer forms a series resonant circuit. Especially at
frequencies > 50 / 60 Hz this may result in voltage superelevation.
►
When testing capacitive test objects using voltages
≥
500 V, make sure that the
test object’s capacity does not exceed 25 nF.
►
Never use
Quick
to measure the resistance of windings with a high inductance.
Turning off the DC source results in life-threatening voltage levels.
►
For this kind of measurement only use the special winding resistance test card
RWinding
or the test card
TRTapCheck
.
