Name of the Experiment:

To Study the 2-wire DC Distribution feed at one end and calculate the various load current.

Apparatus Required:

1. Trainer kit.

2. Patch chords.

Diagram:

Theory:

Procedure:

1. Connect positive lines of S₁ to T₁ and common point of the G (GND terminal to G.

2. Connect voltmeter between T₁ and G.

3. Connect ammeter terminals in series connection positive line of respectively.

4. Connect  feeder terminal T₂ to R₁ through Ammeter.

5.Connect  another end of  R₁  to common point of G.

6. Connect  feeder terminal T₃ to R₂ through Ammeter.

7.Connect  another end of  R₂  to common point of G.

8. Connect  feeder terminal T₄ to R₃ through Ammeter.

9.Connect  another end of  R₃ connect to common point of G.

10. Connect  feeder terminal T₅ to R₄ through Ammeter.

11.Connect  another end of  R₄ connect to common point of G.

12. Verify the connection as per the connection diagram and connection procedure.

13. Switch ON/OFF the power switch.

14. Note down the various ammeter reading and tabulate it.

15. From that find out the various potential drop between feeder terminals using voltmeter/ Mutimeter.

16. Calculate the voltage drop of feeder T₂, T₃, T₄, T₅  by using the line current I₁, I₂, I₃, I₄ and the resistance of the line.

17. Verify the measured value and calculated value.
