News - How does smart meter realize anti-tampering?

In addition to  the conventional  metering function, the remote smart  electricity meter also has variety of intelligent functions. So can a remote smart electricity meter prevent power theft? How to prevent electricity theft? The following article  will answer your questions.

Can a remote smart meter prevent power theft?

Of course  it can!  Power theft could be:

1) Magnetic interfering  power (steal electricity by interfering the operation of the internal components of the meter with magnetic force)

2) Remove the voltage power (remove a line voltage of the meters)

3)Install electric meter reverser  ( change the current, voltage,  Angle or size of the phase with reverser), etc.

How to prevent remote smart  electricity meter from being  stolen electricity?

Take the remote remote electricity meter of Linyang Energy  as an example to explain how to prevent power theft.

1. The measurement of remote smart electricity meter is not affected by magnetic force.

The remote smartt electricity meter of Linyang takes the real-time sampling of the user’s power supply voltage and current, and then integrates  the circuit of the electricity meter to convert it into a proportional pulse output, which is processed and controlled by the single chip microcomputer to display the pulse as the electricity consumption and output to realize the electric energy measurement.

From the perspective of metering principle, the metering principle of remote smart electricity meter is completely different from that of conventional  electricity meter, which is independent of magnetic field. Interference of magnetic field to steal electricity can only target at traditional electricity meter, and it is useless for remote smart electricity meter.

2. The event recording function of remote smart electricity meter can help utility  check power theft at any time.

The meter will automatically record the programming, closing, power loss, calibration and other events as well as the status of the meter when the event occurred. If someone changes the line voltage or installs the meter reverser, it can easily find out whether the power is stolen from the data such as the user’s electricity record, the meter’s cap opening record, the times of each phase’s voltage loss and current loss.

3. Remote Smart  electric meter makes alarm for abnormal circuit events 

The integrated smart meter has built-in anti-reversing device and monitoring function, which can measure the operating parameters such as voltage, current (including zero line), active power and power factor, and the reversal of the meter will not exceed one turn. In addition, if the meter  has  abnormal circuit such as voltage phase failure, voltage loss, current loss, power loss, super power and malignant load, the meter will send an alarm signal to customers and trip automatically.

4.Effectively protect smart electricity meter with sealing and meter box 

Every electricity meter has a seal when it  was delivered from the factory. If you want to dismantle the meter and modify the meter, you must break the lead seal. In addition, most of the electricity meters are installed in the electricity meter boxes and sealed off. It is very difficult for users to directly touch the electricity meters as before, so they have little chance to do anything and are easy to be found.

5. Smart electricity meter + remote meter reading system can prevent power theft in real time.

Remote meter reading system can  control all electrical equipment including running status and  data. All electricity data  could be  remotely  real-time monitored and dimensional analyzed. If you have found abnormal event, the system will immediately send  a warning notice  through computers, cell phones, text messaging and other ways and automatic trip the meter.  The managers can  quickly find out the abnormal reason and solve problems and effectively prevent the  accidents and power theft.
