Here i will try to demystify the ct pt confusion. Below are the the connections diagrams for installation of a single phase 3 phase 4 wire kwh meter digital or analog energy meter from the supply to the main distribution board in home. Hi i have contacted c t to ammeter of range 50a ct ratio is also as per mentioned on ammeter ie 50 5 i have passed loading wires 2nos of one phase through c t.
Three phase keypad prepayment energy ct pt connected low voltage metering cabinet mcu metering control unit installed in.
Similarly i have contacted to other two phases but none of the ammeters are showing the reading except slight deflection in 2 meters what may be the problem. The setting may be different in other type of kwh or energy meter in different locations around the world. This example shows the most common used arrangement in the world but there are variations as well in some areas. In the above diagram i shown an utility pole form which i get supply to kilowatt hour e meter and after that i get supply form energy meter.
