Three resistors are connected in delta. If the line voltage is 13.2kV and the line current is 1202 A, calculate the following:
A) the current in and the voltage acroos each resistor
B) The power supplied to each resistor and the 3 phase load
C) The ohmic value of each resistor
Derive the component transformation equations for tensors shown below where [C] = [BA] is the DCM (direction cosine matrix) from frame A to B.
^B [T] = [C]^A [T] [C]^T
With the aid of a phasor diagram show that the active
power and power factor of a balanced three-phase load
can be measured by two wattmeters.
For a certain load, one wattmeter indicated 20 kW
and the other 5 kW after the voltage circuit of this
wattmeter had been reversed. Calculate the active
power and the power factor of the load.
ANS:
15 kW, 0.327
