If the capacitance between two conductors of a 3 phase line is 6 μF, the capacitance of each conductor to neutral will be

The correct answer is option  2):(12 μF)

Concept:

If the capacitance between two conductors A,B of a 3-phase line is given as C_AB

The capacitance of each conductor to neutral will be C_AN,C_BN which is also called phase capacitance

C_AN or CBN = 2 × C_AB

Calculation:

Given 

C_AB =  6 μF

CAN or CBN = 2 × CAB

= 2 × 6

= 12  μF
