what is HVDC, what are advantages over conventional system?
HVDC means High Voltage Direct Current...
Some of the advantages are can transmit high voltage. No
reactive and capacitance as in AC.Transmission cost is
less... Even one conductor is enough with another conductor
is earthed.Control of magnitude is possible.
Interconnection of asynchronous networks is possible..

how much resistence in proper earthing?
why do motors burn out? I understand why adding parallel loads to a power source means more current moves through the circuit, and can destroy circuit elements by overheating. What about when you have a vaccuum cleaner intake flush against a floor, a room fan sitting directly against a wall, or a power drill trying to drill through something too hard?
If I need to purchase a step-down transformer (from three phase 33kV 50Hz to 400/230V), what additional information do I need from the main supply power line?
