engineering recuitment HPCL Junior Executive 2025 Mock Test Electrical and Electronics Measurements Measurement of Power Measurement of Poly Phase Power
W1 and W2 are the readings of two wattmeter to measure power of a 3 phase balanced load. The reactive power drawn by load is:
1
W1 + W2
2
W1 - W2
3
√3(W1 + W2)
4
√3(W1 - W2)
