Transcribed Image Text:

(b) Electrical power is delivered to a Glass-Ceramic Plant, as shown in Figure 3.2 on page 4. The frequency of the voltage source is 50 Hz. The Glass-Ceramic Plant has the following loads: • • Inductive loads absorbing 4300 kVAR at a power factor of 0.67 lagging. Resistive loads absorbing 3100 kVA at a power factor of 0.92 lagging. Capacitive loads absorbing 130 kW at a power factor of 0.58 leading. Note: Question No. 3 continues on page 4. 3 ATTENTION: The Singapore Copyright Act apples in the ues of the doument. Nonyming 22/0° kV(rms) 50 Hz =C Figure 3.2 Glass-Ceramic Plant y nuty EE2001 (i) Find the total complex power of the Glass-Ceramic Plant. (ii) Find the value of the capacitor C in Figure 3.2 that will correct the power factor seen by the 22 kV voltage source to 0.95 lagging. 42.3G
