Hi we are using Siemens S120 chasis module blocks. In This we are facing F30021 Ground fault. 6SL3330-7TE36-1AA3 (6SL3352-1AE36-1CA1/6SL3352-1AE36-1EA1) 6SL3330-7TE35-0AA3(6SL3352-1AE35-0AA1) 6SL3330-7TE41-0AA3(6SL3352-1AE41-0FA1) 6SL3320-1TE38-4AA3 6SL3320-1TE36-1AA3 CT- Current transformer, Below LEM make CT we are using 1)LEM LF 1005-S/SP36-----1000Amp 2)LEM LF 505-S/SP27-----500Amp In both converters and Inverters CT's are getting failed. So what can be the reason for these failures. This system is runninf from Last 10 years. Is this beacuse of aging of Current transformers. Please support. ------------------------------------------------------------------------------------------ |
