​The signal can be directly connected from the current and voltage transformers. The PT/CT ratio can be set arbitrarily. The meter displays scrollable settings.

​The three-phase multi-function energy meter is designed for the power monitoring needs of power systems, industrial and mining enterprises, public facilities, and smart buildings.

The meter has been inspected and sealed before leaving the factory, and it can be installed and used. If there is no lead seal or it has been stored for a long time, the relevant d

​The electromagnetic element of the three-phase four wire active and reactive watt hour meter is a separate structure. The voltage movement adopts a closed sample movement made of

​This meter is used to measure the three-phase four-wire AC active energy with a rated frequency of 50HZ and a reference voltage of 3×220/380V.

If it is found that it is a lead-free or expired watt-hour meter, please ask the relevant department to re-calibrate before installing and using it to ensure accurate measurement o

​In low-voltage three-phase four-wire lines, three-element three-phase watt-hour meters are commonly used. If the load current on the line does not exceed the range of the watt-hou
