Connects to the CTs
Without interrupting service or changing the existing installation.
Medium and large loads
Indirect three-phase meter (MIT)
Indirect metering for large customers and transformer substations.
On the outside, it looks just like the direct three-phase meter. Metering is done with external current transformers: when consumption exceeds 100 A, this is the device.

Indirect metering
Use the transformers you already have
The meter works with standard current transformers with a 5 A output, the same ones already installed in most large-customer metering points. If needed, AMIAR also supplies them with immediate delivery.
Ask about current transformersMeasures in four quadrants
Active and reactive energy per phase, consumed and generated.
Separates by time-of-use band
Accumulates peak, off-peak and shoulder with the maximum demand for each.
Reports to the platform
Over the Mesh network, with the total per phase and cumulative consumption.
Features
For customers who can't afford failures
