The major power-system loss is probably the loss in the resistance of power cables, both overhead and underground.
The power loss can be reduced by using a thicker wire, at a greater cost for purchase of the wire. Obviously there is an optimum, minimum-cost size for the cable. A theory for deciding it is called Kelvin's Law.
Overhead cable usually have a cross-section area of 150-400 mm-squared.

How did crusades affect the government economy and culture of Europe?
It eliminated the feudal system in Europe. Which gave increased power to the king.
Explain the power flow diagram of induction motor?
The input power, Pin, is reduced by different loss sources in the system. These reductions are the difference between input power & output power. The losses are: PSCL: Stator copper losses, or I2R losses Pcore: Core losses PRCL: Rotor copper losses PF&W: Friction & windage losses Pmisc: miscellaneous losses All of these losses reduce the input power. The output power is the input power minus all of the losses. Pout = Pin - PSCL - Pcore - PRCL - PF&W - Pmisc
What is Deregulation of power system and what are the effects of deregulation?
Restructuring the existing power system network to achieve better utilization of electrical energy with reduction of losses
What is use of slack bus in ac power flow and dc power flow sepratly?
For make a system balanced losses in power
How do you calculate copper losses?
copper losses are power losses due to flow of current in the wires or resistances,if the resistance is R, current is I then copper losses are I2R. for a 3-phase system; copper losses are same but for a single line, total losses are 3I2R.
what are the advantage and disadvange of power system stability?
Advantages Of Power System Analysis By analyzing the system, the life span of equipment increases. Power or electricity can be delivered properly without any losses. Safety factor increases The efficiency of power or electricity transmission increases. Disadvantages Of Power System Analysis Risk is more 24 hours of monitoring is required.
Is reactance major responsible for power loss in power transmission lines?
Reactance certainly causes loss in a transmission system, but I^2R or resistance losses are greater.
Need of a voltage regulation in power system?
no maintain voltages from no load to full load depending on demand and to reduce losses
