1. Power Flow (P and Q):
o T1: 20.8 MW and 15.7 Mvar on the high side, and 20.7 MW and 12.8 Mvar on the low side, indicating transformer losses of 0.063 MW and 2.82 Mvar.
o T3: 25.8 MW and 20.5 Mvar on the high side, and 25.7 MW and 15.9 Mvar
on the low side, indicating transformer losses of 0.101 MW and 4.53 Mvar.
1. Voltage Levels:
o Both transformers are stepping down the voltage from 132 kV to 11 kV.
o T1 has a voltage of 10.3 kV on the secondary side.
o T3 has a voltage of 10.1 kV on the secondary side, likely due to the higher loading condition.
2. Transformer Loading:
o T1 is operating under normal conditions, hence the voltage drop and losses are minimal.
o T3 is fully loaded, leading to higher losses and a larger voltage drop, indicating the impact of increased load on transformer performance.
3. Load Conditions:
o Lump10 and Lump12 represent loads connected to the secondary side of each transformer.
o Lump12 has a higher capacity (25 MVA) and current (1312 A) compared to Lump10 (20 MVA and 1050 A).
In summary, the ETAP model illustrates the power flow and loading conditions for two transformers. The left transformer (T1) is under normal load, while the right transformer (T3) is fully loaded, demonstrating the effects on voltage, losses, and power flow under different loading conditions.
