Voltage Transformer
5 - 11
– To save the measurement press K
EEP RESULTS (pressing the I/O push-
button has the same effect). The last measured values are "frozen", and can
now be assessed.
– Stop the manual test by pressing the I/O (test start/stop). The test can now
be assessed.
– To repeat the test, first press B
ACK TO T OP, if applicable, and then C LEAR
R
ESULTS.
2. Option "Manual input" selected
Manual test
Clearing "Auto" lets you set the test voltage Vtest manually with the handwheel.
– Press the I/O (test start/stop) push-button to start the test. The focus is set
onto the "V test:" entry field.
– Set the value of your choice either by turning the handwheel and/or by
entering it with the numerical keys.
– Vsec is measured and displayed.
– To save the measurement press K
EEP RESULTS.
– Navigate to the "I sec:" entry field
– Enter the measured Isec value either by turning the handwheel or by entering
this value with the numerical keys, and press E
NTER or the handwheel to
acknowledge your setting.
– Now the burden is calculated and displayed.
Note: Select "Manual input" prior to starting the test. If the test card still
contains results, clear them by pressing C
LEAR RESULTS.
When "Manual input" is selected, there is no phase available.
Consequently, neither the phase angle
ϕ nor cosϕ can be calculated.
Since an automatic test only lasts a very short period of time, and a
manual measurement is rather difficult, an automatic test with a
manual measurement is not useful. Therefore, this Reference Manual
will not cover this subject.
Note: A value set with the numerical keys needs to be fully entered and
acknowledged by pressing either E
NTER or the handwheel before
it is applied to the output. If needed, it can then be adjusted using
the handwheel.
Values set by turning the handwheel are applied instantaneously.
