Product features and scope of use

This product is composed of three-phase two-element combined transformer and instrument box. The three-phase two-element combined transformer is composed of a single-phase voltage transformer (PT) and two current transformers (CT). PT and CT are both Electromagnetic type, two PT windings are composed of V/V connection method, three-phase measuring device, and the primary windings of two CTs are connected in series with phase A and phase C of the grid respectively. In the metering part, there are two three-phase active and reactive energy meters each with an inverter to realize the electric energy measurement of forward power transmission and power transmission.
Once connected to AP1-AP2, CP1-CP2 is a large current ratio, and when connected to AP1-AP3, CP1-CP3 is a small current ratio.
For example: 50-100/5, once connected to AP1-AP2, CP1-CP2 is 100/5, once connected to AP1-AP3, CP1-CP3 is 50/5.
The product has: low magnetic density, wide load, anti-theft electricity metering box with multiple current ratios, in the state of bidirectional power transmission, no matter when the load interval changes greatly, the high precision of 0.2S can accurately measure electric energy and so on.
