What is the effect of excessive voltage drop on electrical appliances in a DSS?

Excessive voltage drop in an electrical system, such as a Dually Supply System (DSS), can lead to possible malfunction or damage to electrical appliances. When the voltage drop is significant, the appliances may not receive the voltage they require to operate effectively. This under-voltage condition can lead to erratic operation, reduced performance, and even permanent damage to components. For instance, motors may not start or may run poorly, and sensitive electronics can malfunction due to insufficient voltage levels.

Electrical appliances are designed to operate within specific voltage ranges. Deviations can cause stress on the internal components, leading to overheating, increased wear, or outright failure. Therefore, managing voltage drop is crucial to ensuring the longevity and proper operation of electrical appliances within any system.

In contrast, the other options imply outcomes that do not occur due to excessive voltage drop, such as enhanced efficiency, increased safety, or improved reliability, all of which are undermined by inadequate voltage supply to appliances.
