Question
When the three identical star-connected
coils are supplied with 400 V, 50 Hz, 3-phase
supply, the 1-phase wattmeter whose current
coil is connected in line R and pressure coil
across the phase Rand neutral reads 6 kW
and the ammeter connected in R-phase
reads 30 Amp. Assuming RYB phase
sequence find: (i) the power factor, of the
load, (ii) resistance and reactance of the
coil (iii) reactive power of 3-phase load and (iv)
Apparent Power
