Do sensing relays monitor AC voltage output and can they affect load transfer during inverter failure?

• A. True
• B. False

Answer: (A)

Sensing relays are designed to monitor the electrical parameters of a system, including AC voltage output. They play a crucial role in detecting any variations or abnormalities in voltage levels. When there is an inverter failure, the sensing relays can respond to this situation by switching to an alternate power source or implementing a load transfer mechanism to maintain the reliability of the system. This means that they actively participate in managing the power distribution to ensure that the load continues to receive the necessary power, thereby mitigating any potential disruptions caused by inverter issues. Therefore, it is accurate to say that sensing relays monitor AC voltage output and indeed can affect load transfer during inverter failure.
