engineering recuitment PGCIL Diploma Trainee Mock Test 2024 Electrical and Electronics Measurements Measurement of Power Measurement of Poly Phase Power
For a balanced load, the reactive power is measured by two wattmeter method with readings W1 and W2, the total reactive power is given by:
1
(W1 - W2)
2
(W1 + W2)
3
\(\sqrt{3}(W_1-W_2)\)
4
(W1 + W2)/\(\sqrt3\)
