Consider a three phase, 50 Hz, 11 kV distribution system. Each of the conductors is suspended by an insulator string having two identical porcelain insulators. The self capacitance of the insulators is 5 times the shunt capacitance between the link and ground. Find the voltage across the two insulators V1 and V2? (V1 = Voltage of disc nearest to the conductor)

• A.  V1 = 2.89 kV and V2 = 3.46 kV
• B.  V1 = 6 kV and V2 = 5 kV
• C.  V1 = 5 kV and V2 = 6 kV
• D.  V1 = 3.46 kV and V2 = 2.89 kV

Answer: (D)
