EM4300 not providing RMS current measurement

In the datasheet it is stated that Current per Phase is measured but the current measurement is not available in the COMX.

We have only maximum current over demand, which I guess is the maximum current recorded by the EM over  all 15 minutes windows since start-up.

Same thing for Voltage measurement, only L1-N voltage is shown, no measurement regarding L2, L3 and only Minimum

Is-it normal ?

Kind regards

Hi Guillaume,

Please refer to chapter 5 of the EM4300 series user manual for a list of measurements accessible through the Com'X series gateway:
EN: PowerLogic™ EM4300 series user manu | Download Schneider Electric
FR: EM4300 series user manual -FR | Download Schneider Electric

Hope this helps,

Cesar

It does not help because on this page :

METSEEM4320 - PowerLogic EM4300 Energy Meter - 2000A - Zigbee communication - class 1 | Schneider El...

it's written :

type of measurement

Active and reactive power

An not transmitting 3PH current, and 3PH Voltage

Unfortunately, the EM4300 series only support maximum current and minimum voltage.  3-phase measurement support is only for energy, power and PF.
