Procedure for transformation ratio


1.I have created an winding group with low votage current transformer with primary current as 200 and secondary current as 5.

2.Then created an device category with an transformer and assigned the winding group to transformer.Then created a device with the transformer.

3. Then i have created a device category with meter and assigned the register group with the direct measurement.then created a device with the meter.

4.then i have made the made the installtions.

5.When i do the device allcation ,with controlling device and controlled device,the system is asking for the allocation type.but when i select the transformation group as device allocation type the system is not accepting to proceed further.

Can any one correct me if am wrong in the procedure.

Or can any one explain me how the transformation ratio works with procedure.

Thanks in advance.

    if you are using a low voltage current transformer ... you should use a device category for meter with semi-indirect measurement ... this would work just fine
