Welcome to the Schneider Electric Global Website×
If the meter is being provided a very small current (0.005A/5mA or less) on the secondary side, the meter will read 0 for the phase current.
Since kW is dependent on the current reading this value will also be zero.
To find out what the minimum Primary starting current is you can calculate as follows:
Primary_Min_Current = 0.005 * CT_Ratio
Where CT_Ratio = CT_Primary/CT_Secondary
CT Ratio = 2000:5 (Primary:Secondary)
Starting Current = 0.005A (Secondary)
CT_Ratio = 2000/5 = 400
Primary_Min_Current > 0.005 * 400 = 2A (primary side load).
