The hotel power failure meter rang.

The sound made by the internal mechanical parts of the electric meter during operation. It is normal for the electricity meter to make noise after the power failure in the hotel, because the mechanical parts inside the electricity meter make noise when working. There is a rotating wheel inside the meter, which will rotate with the flow of current, thus recording the electricity consumption. When the power is cut off, the runner will stop rotating, but due to inertia, the runner may still maintain a certain rotating state, resulting in clicking or noise inside the instrument. Hotels (also known as hotels, hotels, inns, guest houses, business trips, inns, hotels in China, and hotels in Malaysia and Singapore) are basically defined as business organizations that provide safe and comfortable spaces for users to have a short rest or sleep.
