Study of Current Transformer (C.T.) Manufacturer,Supplier and Exporter in India

Product Code : SCL-EELE-12928

Indian Lab Suppliers supplies the Study of Current Transformer (C.T.) (Product ID: 12928) as part of its electronics engineering lab equipment range. It shows how a 10:1 current transformer scales a load current of up to 2 A down to 200 mA for measurement.

Quick Answer

The CT primary carries the current of up to three 100 W lamps, each with its own switch, while two 3½-digit digital AC ammeters read the primary (0-2 A) and secondary (0-200 mA) currents. Students compare the two readings at each load and confirm the 10:1 ratio. The board runs from 230 V, 50 Hz mains with a 1.5 A fuse. Never open the CT secondary while the primary carries current, because a dangerously high voltage can appear across it.
