11 KV CTs & PTs , Out door Pedestal mounting versions will do. Current ratio , STC Rating & Insulation level can be determined with connected load. Like breaker / Transformer Etc. Example : Load is 11KV 100KVA transformer is connected . Then use 11KV Cts CTR: 5/5 Amps , Class 0.5 for metering , Class : 5p10 for Protection . OCF - 150XI nominal . Oil cooled CTs for MUSS. If it is mounted inside panel / Control room then Use Resin cast type.  SHIVADATHATHRI- 9632153842.
