In order to ensure the accuracy, safety and reliability of the electric energy metering device, the standardization of metering wiring must be considered. So, what wiring rules must be paid attention to when installing the electric energy metering device composed of different types of smart meters, current transformers and voltage transformers?

1. The electric energy metering device connected to the neutral point insulation system should use three-phase three-wire active and reactive energy meters, such as Holley DSS533 three-phase three-wire electronic electric energy meter distributed by Hunan Jishe, and Holley DSZY719 three-phase three-wire fee-controlled smart meter. (Neutral insulation system: refers to a system in which there is no connection to ground other than by an indicator, measuring instrument, or protective device with high impedance.)

2. If it is connected to the non-neutral point insulation system, a three-phase four-wire active and reactive energy meter or three inductive non-invertible single-phase energy meters shall be used. For example, Wasion electricity meter three-phase DTZY545-Z, DTSD341, single-phase DDS102, etc.

What wiring rules must be paid attention to when installing an energy metering device?

3. The three voltage transformers connected to the neutral point insulation system, 35kV and above should be wired in the V way.

4. Three voltage transformers connected to the non-neutral insulation system, 35kV and above should be wired in Y0 Y0 mode. The primary side wiring method is consistent with the system grounding method.

5. When the load current of low-voltage power supply is 50A and below, it is advisable to use a direct-access electric energy meter. For example, Wasion electricity meters DDS102, DDSF102-Z, DDSY102, etc. If the load current is more than 50A, it is advisable to use the wiring method connected through the transformer.

For example, Wasion electricity meter DTZY341-Z, DTSD341 and other three-phase meters.

6. For the three-phase three-wire wiring electric energy metering device, the secondary winding of the two current transformers and the electric energy meter should be connected by four-wire.

7. For the three-phase four-wire wiring electric energy metering device, the secondary winding of the three current transformers and the electric energy meter should be connected by six wires.
