113.xxx Warning [113.xxx] Test not successful. Kneepoint not found.
Reason: Knee point for specified standard not found.
Solution: The current required to reach the knee point for the specified standard cannot
be delivered. The CT cannot be tested up to the knee point voltage.
114.xxx Warning [114.xxx] Low inductance detected during excitation measurement.
Reason: Low inductance was measured during the excitation test.
Solution: Verify that the primary side of the CT is not short-circuited.
This warning can also occur for CTs with very low excitation loss and high
parasitic capacitance.
115.xxx Warning [115.xxx] Invalid eddy loss measurement.
Reason: Reliable determination of the eddy losses is not possible.
Solution: Verify the wiring and repeat the test. If the error message is displayed
repeatedly, it is currently not possible to test this CT using the CT Analyzer.
116.xxx Warning [116.xxx] Knee point too low! CTs with a knee point below 1 volt are not
supported.
Reason: The knee point voltage is smaller than 1 V.
Solution: Currently it is not possible to test CTs with such a low knee point using the
CT Analyzer.
121.xxx Warning [121.xxx] Test not successful! Reverse polarity. Check wiring and repeat the
measurement.
Reason: Measured polarity is wrong.
Solution: Reverse the polarity of the measurement cables on the primary or secondary
side of the CT.
130.xxx Warning [130.xxx] Burden impedance > 1kOhm.
Reason: Burden impedance > 1k
Ω.
Solution: The test cannot be continued. Check the connections to the Burden.
131.xxx Warning [131.xxx] Overload during Burden measurement.
Reason: The required test current cannot be reached, even at the maximum output
voltage.
Solution: The CT Analyzer cannot deliver enough current. Reduce the test current or the
impedance of the burden. Check the wiring for proper contacts; one connection
possibly has a bad connection.
140.xxx Warning [140.xxx] Timeout during remanence test. Measured magnetic flux is unstable.
Reduce noise level.
Reason: The magnetic flux during remanence measurement is not stable.
Solution: The test cannot be continued. Check the connections to the CT. Try to reduce
the noise level for the measurement.
200.xxx Warning [200.xxx] Check connection. Make sure burden is properly wired.
Reason: The measured input voltage differs by more than 5V from the input voltage
expected during burden test.
Solution: Check whether the output generator ("Output") and measurement input "Sec"
are connected correctly.
200.xxx Warning [200.xxx] Check CT SB2 switch box wiring: CTA OUTPUT and/or BURDEN
terminal may be disconnected.
Reason: The measured input voltage differs by more than 5V from the input voltage
expected during the burden test using the CT SB2 switch box.
Solution: Check whether the BURDEN OUT and the BURDEN IN sockets on the CT SB2
are connected correctly.
