The current coil of wattmeter is connected to the CT of R-phase. The potential coil is connected across Y and B phases. The wattmeter will measure

  1. Active power in R phase
  2. Active power of Y phase
  3. Power that is proportional to 3 phase power if load is balanced
  4. Reactive power of R phase

Correct answer: 4. Reactive power of R phase
