Smart electricity meters offer higher measurement accuracy and sensitivity than traditional inductive mechanical meters, enabling them to detect minute currents-such as the standby power consumption of household appliances-that older meters are unable to register.
While smart meters do indeed consume a certain amount of electricity during operation, this consumption is borne by the power utility company and is not charged to the user. Users can verify this by switching off their home's main power breaker and observing whether the meter's pulse indicator light continues to flash.
The metering speed of a smart electricity meter cannot be artificially manipulated or tampered with through external means-such as by placing strong magnets in close proximity or adjusting internal knobs.
From the point of manufacture to final deployment, every electricity meter undergoes a rigorous, multi-stage inspection process that includes internal quality control by the manufacturer, acceptance verification by the power utility company, and supervisory spot checks conducted by government market regulatory authorities.
