MCP3909 / dsPIC33F 3-Phase Energy Meter Reference Design.
To describe how to use the MCP3909 / dsPIC33F 3-Phase Energy Meter Reference
Design, the following example is given using a 4-wire, 3-phase, 220VAC line voltage
and connection. The rated current of the energy meter is 5(20)A.
The energy meters are not shipped fully calibrated, and a full calibration should be
performed to show the true meter accuracy. See Chapter 4. “Meter Calibration” for
more information.
All connections described in this section are dependent on the choice of current
sensing element and a secondary external transformer may be required in higher
current meter designs.
