schneider easylogic pm2100

Hi All,

I have installed a Schneider EasyLogic PM2100 energy meter in one of my panels and configured all the basic parameters. The meter is displaying the real-time values for voltage, current, and power factor correctly. However, it is not recording the energy consumption accurately.

The average values over a one-hour period are as follows:

Voltage: 390 V, Current: 460 A, Power Factor: 0.85

Based on these values, the expected energy consumption should be approximately 264 kWh for one hour. However, the meter has logged only 83 kWh.

Could anyone please advise what might be causing this discrepancy? Any guidance or suggestions would be greatly appreciated.

Thank you.

Hi @alexkjohn20 

This meter provides bi-directional Energy - PM2100

Please check the phase wise power, might be one of the phases showing -ve kW.

Ex: 

R= 10kW, Y= 10kW, B= -10kW
kW Total= 10kW
If that is the case, you have to look for CT polarity connected to the meter.

Thanks & Regards

Hello @alexkjohn20 ,

Please verify the VT/CT configuration and cross-check all phase-wise active power and power factor (PF) readings.

• Negative phase power may indicate incorrect CT polarity or phase mapping.
• Low phase power with low PF may indicate a phase angle mismatch. Review the voltage-current phase angles to help identify wiring or configuration issues.

These checks can help isolate the source of the observed behavior
