Many friends have heard that smart meters run fast, abnormal.  Smart meters are actually more accurate than their predecessors. "Is the smart meter accurate?  For the meter".

I. Are smart meters accurate?   

Smart meters will be faster, Not More Accurate?   

It's not. In early mechanical meters, due to bearing wear and corrosion for a long time, the measurement may be gradually out of alignment, and the "slow" phenomenon is just an illusion generated by comparison before and after changing the meter. Early mechanical meter sensitivity is low, need to reach a certain load, electricity meter will "word". 

II. for the problem of electricity meters  

The meter is still running when all the appliances are off?  

The red light on the meter is still flashing when everything in your house is turned off?  

In fact, many home appliances in standby state is also in power consumption, such as routers, set-top boxes, water heaters, and many smart home appliances...   

To truly power off, you need to directly turn off the circuit breaker below the meter so that the meter's red light does not flash.   

If the red light will be bright in this case, it is necessary to pay attention to, may be the line aging caused by leakage, or be stolen electricity, need to report in time yo!   

Electricity meter is small meter, current assembly more charge?  

Smart meters have signs such as 5(60)A, 5A is the calibration current, 60A is the maximum current allowed by the meter, indicating that the total power of the home can be up to 13.2 kilowatts.  

There is no such thing as a small meter or a large meter.  

Smart meters use their own electricity, but should be included in the electricity bill?  

The current consumed by smart meters is in parallel with the current measured by users, which means that the current required by the meters is not the electricity used by households, but borne by the power supply enterprises themselves.
