My meter is measuring 0A and 0kW but correctly reads the Voltage, what is the issue?

Resolution
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

Example:
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).
