Q5. An essential part of the design of power supply network is the calculation of the currents which flow in the components when faults of various types occur. Explain briefly why fault calculation is an essential part of the design of power systems. Discuss the TWO different types of faults that are common in power systems; their causes; and method of calculation.
A DC is supplied through a solid conductor cable. The fault in the cable can be determined by using Murray Loop Test. The healthy cable has the insulation resistance of 1 kilo Ohms per meter. No fault occurred till the first 10 km. The core of healthy cable has the circumference of 7.86cm. If the resistivity of insulation is 900 G Ohm-mm, what is the diameter of the cable.
