What is the function of a Reverse Current Relay?

A Reverse Current Relay primarily functions to prevent reverse flow of current in electrical systems. This is crucial for maintaining the integrity of the circuitry and protecting equipment from potential damage caused by unwanted current in the opposite direction. In scenarios where there is a possibility for current to flow back, such as in battery systems or power distribution networks, the relay acts as a safeguard, ensuring that current only moves in the intended direction.

The other options do not accurately describe the function of a Reverse Current Relay. While enhancing power supply efficiency and amplifying voltage supply are important in electrical systems, those roles are typically fulfilled by different components such as transformers or capacitors. Additionally, converting DC to AC voltage is the function of an inverter, which is distinctly different from the role played by a Reverse Current Relay. Thus, recognizing the specific protective function of the relay clarifies its importance in maintaining system stability.
