Electrical Meter Current Transformers Wiring Diagram. Its submitted by organization in the best field. Electrical meter current transformers.
In digital amp meter have 4 terminals or connection points in which two connection points for 220 voltage supply which operate the display circuit. In the above diagram i shown three ammeters current transformers in the above ct wiring diagram i common a wire of all ct s my means that i connect ct one connection with one another. It is not always possible to measure the consumed electricity through a meter connected directly to the power network into a wall outlet.
A current transformer is required for each metered circuit so a three phase four wire installation requires three current transformers whereas a three phase three wire installation needs only two.
In digital amp meter have 4 terminals or connection points in which two connection points for 220 voltage supply which operate the display circuit. Meter multipliers current transformers and voltage transformers example. Polarity must be observed when fitting current transformers. In the above diagram i shown three ammeters current transformers in the above ct wiring diagram i common a wire of all ct s my means that i connect ct one connection with one another.
