Why Do Smart Meters Have An Automatic Power-off Mechanism For Over-power Consumption?

smart energy meter, as an important digital metering device in modern power systems, integrates real-time measurement of current, voltage, and power, and possesses remote communication capabilities. 3 phase smart meter not only sends electricity consumption data to the power company but also reacts to abnormal power conditions, including the ability to trigger automatic power cut-off when power consumption exceeds a set value.

Power systems need to handle various dynamic load states during power supply. When the power consumption of a certain line or user exceeds the meter's carrying capacity, the internal control logic of the three phase smart meter will identify the over-power situation. Based on the built-in measurement module and algorithm, this condition is considered a potential risk, triggering the power cut-off control module.

This power cut-off is not a simple circuit breaker trip, but a response through 3 phase wifi energy meter the metering and control unit itself. Over-power events are usually caused by the simultaneous operation of high-power appliances or line short circuits. The single phase wifi energy meter device can continuously collect current and voltage data and determine whether a preset threshold has been reached under internal logic rules. Once the threshold is exceeded, a control signal is sent to cut off the output, thereby achieving local power isolation.
