The expression for voltage regulation of a short transmission line for lagging power factor is given by: ___, where, 'I' is the line current, 'V_r' is the receiving end voltage, 'R' is the line resistance and 'X' is the line reactance.

(IR cosφ_r - IX sinφ_r)/V_r

(IX cosφ_r + IR sinφ_r)/V_r

(IR cosφ_r + IX sinφ_r)/V_r

(IX cosφ_r - IR sinφ_r)/V_r

(IR cosφ_r - IX sinφ_r)/V_r

(IX cosφ_r + IR sinφ_r)/V_r

(IR cosφ_r + IX sinφ_r)/V_r

(IX cosφ_r - IR sinφ_r)/V_r

The current flowing to a balanced delta connected load through line 'a' is 15 A when the conductor of line 'b' is open. With the current in line 'a' as reference, compute the symmetrical components of the line currents. Assume the phase sequence of 'abc'.

Ia₀ = 0 AIa₁ = (7.5 + j4.33) AIa₂ = (7.5 - j 4.33) A

Ia₀ = 0 AIa₁ = (7.5 + j4.33) AIa₂ = (-7.5 - j4.33) A

Ia₀ = 0 AIa₁ = (-7.5 - j13) AIa₂ = (-7.5 - j4.33) A

Ia₀ = 0 AIa₁ = (7.5 - j13) AIa₂ = (7.5 + j13) A

Ia₀ = 0 AIa₁ = (7.5 + j4.33) AIa₂ = (7.5 - j 4.33) A

Ia₀ = 0 AIa₁ = (7.5 + j4.33) AIa₂ = (-7.5 - j4.33) A

Ia₀ = 0 AIa₁ = (-7.5 - j13) AIa₂ = (-7.5 - j4.33) A

Ia₀ = 0 AIa₁ = (7.5 - j13) AIa₂ = (7.5 + j13) A
