               The Medium Voltage Application Catalogue is a tool for all Medium Voltage
               equipment designers.



               Purpose
               b To help you produce Medium Voltage switchgear assemblies which include
               Schneider Electric components
               b To help you specify standard solutions.



               How?
               By offering you standard applications for the protection of different Medium
               Voltage network configurations.
               By providing you with a guarantee of the full protection chain composed
               of different Schneider Electric components.

               b With specification of the equipment required for each standard application
               b And the complete wiring diagram of the Medium Voltage equipment
               for each application.

                Step 1: Selection table
                Using the selection table, you select your application from the different
                standard applications offered:

                b Based on the network component to be protected:
                substation incomer or feeder, transformer, motor or generator
                b Based on the formulated protection, metering and monitoring
                requirements
                The application chosen from the selection table is detailed in the application
                pages.



                Step 2: Application page
                Each standard application is presented in a page which includes:

                b A single-line diagram of the application, with the different components
                to be combined:
                v Switching device
                v Measurement sensors
                v Protection unit
                v Details of the functions offered by the protection unit:
                v Protection functions
                v Monitoring and control functions
                b Optional functions available
                b Reference of the complete wiring diagram for the application.



                Step 3: Wiring diagrams
                A diagram library on CD-ROM contains the wiring diagrams,
                in AutoCad format, of all the standard applications offered.

                Each diagram:
                b Corresponds to a standard application
                b Contains all the information required for the complete wiring, power
                and control current, of the Medium Voltage equipment
                b May be easily adapted by you to match the options you choose
                and your particular needs.
