Part 2: Under load Tap Changer Transformer (LTC): Section 1: Manual Mode 1. Change the transformer's taps in discrete steps, with each step changing the tap ratio by 0.625%. 2. Adjust the tap under load in steps as shown in table 2. 3. Record the Load bus voltage as the tap ratio changes. 4. Tabulate your results in the following table. Off Nominal Tap Ratio 0.98750 Load Bus Voltage 0.99375 1.00000 1.00625 1.01250 1.01875 1.02500 Section 2: Automatic Mode 1. Set the transformer control mode to automatic. 2. What value of Tap Ratio that makes the bus voltage equal to nominal value. 3. Vary the Mvar load, Observe the changes happen, Discuss? (Use your Own words)
