Working principle1The working principle of DTSD/DSSD6607 three-phase electronic multifunctional energy meter is shown in the diagram

As shown:

When the electric energy meter is working, the voltage and current are sampled separately by the sampling circuit, and then multiplied by a dedicated integrated circuit for electric energy processing before being sent to the CPU for processing. Finally, the CPU sends the processed data to output devices such as the display and communication parts as needed.

And wiring

2.3.1 The electric energy meter shall be inspected and sealed with lead before leaving the factory. Before installation and use, it is necessary to check whether the lead seal is intact. If the lead seal is intact, it can be installed and used. For electric energy meters without lead seals or stored for too long, relevant departments should be asked to re inspect them. Only qualified ones can be installed and used.32.3.2 The electric energy meter should be installed in a ventilated and dry indoor area, fixed with three screws according to the following diagram

The installation dimensions shown should be drilled on the base plate first, and the base should be fixed on a sturdy, fire-resistant, and non vibrating object to ensure safe and reliable installation and use. In places with pollution or potential damage to the electricity meter, the meter should be protected by a protective cabinet.3 picture

2.3.3 The electric energy meter should be wired correctly according to the wiring diagram. It is recommended to use copper wire or copper connectors for the incoming wires of the terminal box. The screws inside the terminal box should be tightened to avoid burning due to poor contact or thin leads.
