Must a three-phase watt-hour meter have a transformer?

Three-phase electric energy meters are divided into direct access type; access type through current transformer and access type through voltage and current transformer.
When using a low-voltage three-phase power supply and the load current is small, the direct-access three-phase electric energy meter can be used; when using a low-voltage three-phase power supply and the load current is large, the three-phase electric energy meter can be connected through a current transformer ; When using a high-voltage three-phase power supply, a three-phase electric energy meter connected via voltage and current transformers can be used.three phase smart APS electric energy meter
Transformers are electrical devices that convert high voltage to low voltage and large current to small current. Through the use of transformers, the secondary rated current and voltage can be unified, which is convenient for metering, measuring, monitoring and controlling the primary system.
