Analysis and Resolution:

It is recommended to handle as follows—if there are no current transformers available for replacement, the faulty CT can be blocked, and a single CT can be used to input signals to CT1, CT2, and CT3. For the large and small vehicle operating mechanisms, parameters in the parameter table can also be set by changing parameter 2 "CTS Enable" to "false."

 

Note:

1) At this time, it must be ensured that it is a CT fault and not a real overcurrent fault in the circuit before using this method. 2) There must be separate motor overcurrent protection in the circuit. 3) The lifting mechanism must replace the new CT in the short term.
