Cahier technique no 195 - Schneider Electric

4 ConclusionThis Cahier Technique completes CahierTechnique no. 194 in its aim to increaseawareness of all those involved in the processfrom design of an electrical network toimplementation of protections, of the time wastedand the financial losses resulting from incorrectspecification of CTs. In particular, it gives someexamples of errors not to make and leads forsolutions when the original specification is notsatisfactory or when you apparently come upagainst a dead end.It stresses that although communication with theCT manufacturer and particularly knowledge ofinduction levels enables a solution to be foundby playing with equivalences, it is by identifyingthe exact needs at all stages in the process, thatthe optimised solution can be found.We hope that you will find this document useful.Cahier Technique Schneider Electric no. 195 / p.17
