Q1. You have been asked to investigate if a paper mill is in compliance with ER G5/4. It is supplied from an 80 MVA, 33/11 KV transformer with 4% reactance and 1% resistance. The site demand on the utility is 9 MVA. The load is a 6-pulse, three-phase bridge diode rectifier. 1. Read about ER G5/4 2. Calculate for each harmonic, the rms value of current (1), the circuit impedance (Z) and the voltage (V), then sum the THD. [2.5 Marks]

A single-phase, full-wave diode bridge is used to supply power to a resistive load of value R = 75 2. If the supply voltage is sinusoidal, Vs 400 sin ot, calculate the average and rms values of the load current. Calculate the ripple factor for the load current and compare this with half- wave operation. =
A 3-phase full-wave bridge rectifier is built using six power diodes numbered 1 to 6. The phase sequence of the 3-phase source is ABC and the line to line voltage is 440 V. The line to neutral voltage of phase A has an angle of -30 degrees. The anodes of the diodes 1, 2, 3 are connected to phase A, B, and C, respectively, and the cathodes of diodes 1, 2, and 3 are connected to a common terminal that serves as the positive terminal of the rectifier's output. The cathodes of diodes 4, 5, and 6 are connected to phase A, B, and C, respectively, and the anodes of diodes 4, 5, and 6 are connected to a common terminal that serves as the negative terminal of the rectifier's output. If diode 1 is damaged and acts as an open circuit, what would the RMS voltage be at the load?
