Good day
We had a failure of CT in a 6.6KV Motor feeder panel due to one secondary CT wiring connection was loose/Open in the terminal block. Is there any kind of online detection system or relay to detect the open circuit in the CT Secondary circuit. We are using SEPAM 2000 relay for the Protection purpose and I could not find any feature in this relay to detect if any one PHASE current is not available. Since I am doing the study to recommend a solution to avoid CT failures in future, your expert advice is appreciated.
Best regards and Have a great day
