Expert Solution & Answer
To determine
The advantages and disadvantages of the Western Europe power supply system with
240V and United States, Canada power supply system with
120V.
Answer to Problem 31.1DQ
Introduction: The High voltage power transmission is an effective transmission system, with reduced power losses to transfer the power economically and reliably.
Explanation of Solution
The transmission lines have the major power loss are
I2R losses in terms of heat, this losses are proportional to the square of current and resistance of the line. To transmit the same power by increasing voltage level and reducing the current level, the power losses can reduce effectively.
Ploss=I2R
Consider the same power
(P) transmission with these two given systems.
United States and Canada has the standard supply voltage
120V, this is the low voltage and high current transmission line, and therefore the power losses are high, because of high power losses efficiency is reduced. It is uneconomical, non-reliable, and high risk.
Western Europe has the standard supply voltage
240V, this is the high voltage and low current transmission line, and therefore the power losses are very low, due to reduced power losses efficiency will be improved. It is economical, reliable and low risk.
Conclusion: Therefore the Western Europe power supply system has the more advantages than United States supply system and Canada power supply system.
