HVDC

HVDC stands for high voltage direct current in the electric power transmission system. The high voltage direct current system uses direct current (DC) for the transmission of electrical power through transmission lines in contrast with the alternating current that is the AC system. The HVDC is used to transmit bulk power point-to-point through long distances transmission lines. Power is rapidly transferred because the efficiency of transmission lines is greatly increased over long distances due to HVDC lines.

Question

An alternating voltage is applied to a series circuit consisting of a resistor and iron-cored inductor and
a capacitor. The current in the circuit is 0.5 A and the voltages measured are 30 V across the resistor,
48 V across the inductor, 60 V across the resistor and inductor and 90 V across the capacitor.
Find (a) the combined copper and iron losses in the inductor (b) the applied voltage

Answer: [(a) 3.3 W (b) 56 V]

You find that a 25-F capacitor connected to 480 VAC is defective. The storeroom has no capacitors with a 480-VAC rating. However, you find two capacitors rated at 50 F and 370 VAC. Can these two capacitors be connected in such a manner that they can replace the defective capacitor? If yes, explain how they are connected and why the capacitors will not be damaged by the lower voltage rating. If no, explain why they cannot be used without damaging the capacitor.
