  1. A three phase star-connected load is drawing power at a voltage of 0.9 pu and 0.8 power factor lagging. The three phase base power and base current are 100 MVA and 437.38 A respectively. The line-to-line load voltage in kV is ______.
    1. 118.8 KV
    2. 11 KV
    3. 1188 KV
    4. 11588 KV
Correct Option: A

Base current =
(Base KVA)
3 × (KVL)base

⇒ 437.38 =
100 × 10³
3 × (KVL)base

⇒ (KVL)base = 132 KV
Then, line-to-line voltage in KV
= 132 KV × 0.9
= 118.8 KV
