What is the function of a Dual Radial System?

The Dual Radial System is designed to enhance reliability and ensure continuous power supply by consisting of a running and a standby circuit. This system allows for one circuit to function as the primary source of electricity while the other serves as a backup. In case of failure or maintenance on the primary circuit, the standby circuit can immediately take over, minimizing downtime and maintaining electrical service. The setup is particularly valuable in critical applications where uninterrupted power is essential.

The other options do not accurately reflect the operational intent or design of a Dual Radial System. The notion of operating with a single circuit does not align with the redundancy purpose of the Dual Radial configuration. Similarly, accommodating small customers primarily does not represent the primary function of this system, which can be applicable across various sizes of service demands. The creation of a network of interdependent power feeds pertains more to a different network design, possibly focusing on interconnected sources rather than the redundancy provided by dual circuits in a radial setup.
