Electricity meter no-load energy saver circuit diagram

The working principle of the application circuit of this device is shown in the figure. In the watt-hour meter, the voltage coil and current coil are connected to the power grid in parallel. Regardless of whether there is a load in the circuit, the voltage coil is always connected. The CE module can connect the current to the power grid. The problem of empty consumption of the meter is completely solved. When the load RL is connected in series to the current coil circuit, the voltage coil is immediately turned on without affecting the electricity metering; when the load RL is disconnected, the current in the voltage coil is also cut off, so that There is no-load loss.
