NOTE
: If SMART SVC RELAY realizes any difference in current transformer connection with
the previous ones, it automatically makes the stage test after the current transformer test.
If SMART SVC RELAY detects a change in any current transformer direction, it automatically
makes a stage test. If the user wants to end current transformer test due to any reason, the user
must press
ESC key until the test is cancelled. The cancellation of the current transformer test
is specialization-required subject. In the case of cancellation of this test, the user must consider
connection directions and input/output. It is not recommended to cancel the current transformer
test.
The Warning Messages Indicating Connection Errors in Transformer Test
Figure 3.39
Possible causes and solutions according to Figure 3.39:

Monophase capacitors may be connected to the first rows. The user must wait for
relay to draw three-phase capacitors.
Figure 3.40
Possible causes and solutions according to Figure 3.40:

There may be a problem in current transformer or connections of L2 and L3.

The current transformer of L2 and L3 phases are connected to wrong point.

The k-1 tips of k2-12 and k3-13 terminals current transformers, which are attached for
measuring L2 and L3 phases, may be mixed with each other. In this case, the k2-13 tips
must be relocated in the device input and the test must be repeated.

There may be connection errors. The user must follow the connections and fix the errors.

There is not sufficient current in L2 and L3 phases during the transformer test.
