NOVAR 2600 Operating Manual
The test can have up to six rounds with four testing steps each. After each step, the measurement
results of individual phases are analyzed. If the results of any phase is sufficiently stable, detected
current signal connection information is shown in the main line, as can be seen in the picture above in
the L1 phase result. The connection information can be one of following :

CT connection test
result
meaning action required

correct connection none (both phase and polarity correct)
R correct phase,
reverse polarity swap the current input wires
→ wrong phase,
correct polarity move wires to the next phase current
input, keep the polarity
← wrong phase,
correct polarity move wires to the previous phase
current input, keep the polarity
R→ wrong phase,
reverse polarity swap the wires and move them to the
next phase current input
R← wrong phase,
reverse polarity swap the wires and move them to the
previous phase current input
- - -
unsuccessful measurement recheck the connection
As soon as the connection detected at all of phase inputs, the CT test finishes. If all of current signals
connected correctly the test result looks like this :
Fig. 4.18 : CT Test Result – All of the Inputs Connected Correctly
Then you can close the window by pressing of any key, otherwise the window closes automatically
after one minute delay.
If the inputs are not connected correctly, the CT test result can look, for example, like this :
Fig. 4.19 : CT Test Result – the L2 and L3 Inputs Wrong Connected
In such case it is necessary to reconnect the current signals :
• let the L1input unchanged
