State the disadvantages of skin effect.
Disadvantages of skin effect:-
1. Full cross section of conductor is not utilized, Therefore effective area of conductor reduces so its resistance increases.
2. Due to increase in resistance, copper losses increases (Since copper losses = I2R )
3. So transmission efficiency reduces.
4. Due to increase in resistance, Voltage drop increases (Since Voltage drop = IR )
5. So voltage regulation becomes poor (increases)
