The Automatic Power Supply Recovery Mechanism Of Smart Meters

3 phase smart energy meter is not only responsible for electricity metering, but also for transmitting power supply status information in real time, assisting the power distribution system in responding quickly to abnormal situations. When the user-side load is detected to exceed the set threshold or the system is determined to be in an overpower state, the single phase smart meter will initiate power-off logic and interrupt the output through the built-in disconnect switch to protect the circuit and equipment from adverse effects.

Once the high load or high power conditions are relieved, the wifi smart energy meter internal logic will reassess the power supply status. Once the actual load drops to within the allowable range, the metering system will trigger a closing operation to restore the power output to normal. This maintains metering accuracy while ensuring power supply continuity under non-continuous abnormal conditions.
