Description : Series capacitors on transmission lines are of little use when the load VAR requirement is (a) large (b) small (b) fluctuating (d) any of the above

Answer : (b) small

Answer : Series capacitors are used to compensate for line inductive reactance.

Description : In tuned power lines, on load :  (A) the receiving end voltage is numerically equal to the sending end voltage  (B) the receiving end current is numerically equal to the sending end current  (C) there is no voltage drop  (D) all the above

Description : State the effects of low power factor on efficiency and voltage regulation of short transmission lines. 

Answer : i) Effect of Low power factor on efficiency:- When power factor of load reduces current drawn by transmission line increases so copper losses in transmission line increases, hence transmission ... increases, so voltage drop in transmission line increases so regulation increases. (Become Poor) 

Description : State the classification of transmission lines depending on length of transmission lines. 

Answer : A) According to Voltage level: ( 2 Marks)  a) High voltage Transmission Line (HV) up to 33 KV  b) Extra High Voltage Transmission Line (EHV) above 33 KV up to 400 KV  c) Ultra ... Transmission Line: - The length of Long transmission Line is above 200KM and its line voltage is above 100KV
