Answer 2

The correct answer is option (b) Solid grounding.

Explanation:

• Solid grounding system, identification of fault is tedious.
• A system is considered to be solidly grounded when its neutral is connected directly to a station ground or earth with no intentional impedance in that connection.
• Ground fault currents on solidly grounded systems are about equal to three-phase fault currents, and fuses or relays will operate satisfactorily.
• Solid grounding reduce the possibility of over voltages.
• Voltage of the healthy phases remains same as before the fault and thus, less insulation is required for equipment and it results into saving in the cost of equipment.
• It is easy to locate the point of fault.
