Which of the following is NOT a characteristic of a radial distribution system? 

The correct answer is option "2"

Explanation:

• A radial distribution system does not exhibit high reliability because it lacks redundancy.
• Power flows in only one direction, typically from the substation to the end-users, making it vulnerable to disruptions.
• While radial systems are characterized by simplicity and low construction costs, their reliability is compromised compared to more complex distribution networks with multiple paths for power flow, like looped or network systems.
• The lack of alternative routes in radial systems makes them less resilient to faults and failures.
