A single-phase meter shunt is used to measure the line and neutral current of an electrical circuit. The design of this device allows it to function with both configurations, while still maintaining its neutral reference. The main advantage of this type of meter is that it is not subject to the effects of tampering. Here are some of the benefits of single-phase meter shunts. 
Shunts are electrical devices that are commonly used for measuring DC current. The resistance of a shunt is based on the voltage generated across it when a DC current passes through it. They are usually small in size, with four to five mm in diameter. These devices are connected to terminals via screws or elastic washers. The shunt's perforations reduce the area of the metal conductor, reducing the internal conductivity of the current. The result is higher resistance.
The CT current sensor has an associated burden resistor, which must remain connected at all times. This resistor protects the measuring device by ensuring that the current range is accurate. The ADC senses a wide range of current in a single-phase meter, and it will use the current to determine how much energy is being transmitted. It will also determine whether the meter's shunt is functioning in its current detection mode.
This shunt enables the meter to function when the main AC/DC power supply is not functional. If this happens, the meter will not be able to measure active power or RMS voltage. During this time, the backup power supply will have to be used. The reading may be zero, or the meter will not be able to detect the absence of active power. If you remove the neutral connection, your meter will not be able to function properly.
