Using the Quick Test Feature
Use the following wiring for the polarity check (example):
Figure 8-8 Wiring example for polarity check
Note: The CT Analyzer measures the voltage of the injected signal using input
"Sec". Therefore, you should always connect this input when using the Polarity
Check measurement type. The higher the resistance of the wiring checked (i.e.,
the burden wiring) or the current amplitude set on the CT Analyzer, the higher
the terminal voltage generated by this current!
Proceed as follows to perform a polarity check
1. Make sure that the wiring to be checked is disconnected from the
ungrounded side of the CT (see Figure 8-8).
2. Connect the "Output" sockets and input "Sec" of the CT Analyzer to the
wiring to be checked (see Figure 8-8).
3. Open the Quick Test measurement function on the CT Analyzer.
4. Select the Polarity Check measurement type and set the amplitude of the
polarity check signal appropriately.
5. Start the polarity check by pressing the key on the CT Analyzer.
6. The Results Polarity Check card displays the measured values as long as
the measurement is active.
