Select the right answer of the following: 1- The 66 Ky lines use (pin insulators/suspension insulators). 2- The self-capacitance of string insulators is greater than of its shunt capacitance (True/ False). 3- By increasing conductor cross section the effect of corona (Increases/ Decreases). 4- Visual Critical Voltage: It is minimum phase-neutral voltage at which corona glow appears (True/ False). 5- For pin type insulators, the value of safety factor is about 10(True/False).
