STEP 1 : Make Connections as per the instructions given below:
1. R, Y, B and N of MCB - R, Y, B and N of Autotransformer.
2. Z1 of Voltmeter - A1 of Autotransformer and Z2 of Voltmeter - A2 of Autotransformer.
3. A1 of Autotransformer - M1 of Wattmeter and M1 of Wattmeter - C1 of Wattmeter.
4. L1 of Wattmeter - X1 of Ammeter and X2 of Ammeter - Y1 of load.
5. A3 of Autotransfrormer - M2 of Wattmeter and M2 of Wattmeter - C2 of Wattmeter.
6. L2 of Wattmeter - X5 of Ammeter and X6 of Ammeter - Y3 of Load.
7. A2 of Autotransformer - X3 of Ammeter and X4 of Ammeter - Y2 of Load.
8. V1 of Wattmeter - X3 of Ammeter and V2 of Wattmeter - X3 of Ammeter.
NOTE : If wire is wrongly connected, Click on node number to detach the wire.
STEP 2 : Click on "CHECK" button for checking the connections.
STEP 3 : Click on the MCB to Turn ON the supply and Select the number of Bulbs from the Lamp Load.
STEP 4 : Click on "ADD" button to add the readings to the Observation Table.
STEP 5 : Add different readings to the Table by selecting different number of bulbs.
STEP 6 : Click on "PRINT" button to print the webpage.
STEP 7 : Click on "RESET" button to refresh the webpage.
P3Φ = 3VphIphCosΦ, Vph = VL/√3
Where, P3Φ = Three phase power, Vph = Phase voltage,
Iph = Phase current, VL = Line voltage, CosΦ = 1
