Installing the Current Transformers
The three models of PowerHawk meter use current transformers (CTs) with
different secondary outputs. The PowerHawk 6212 meter uses split-core
0.333V CTs (see Figure 9), and the PowerHawk 6312 meter uses 80mA CTs
only (see Figure 10) and is typically used where accuracy is important and
long secondary CT wiring is required (up to 300 feet [91.44 meters]).
For instructions, see “Installing the CTs on the PowerHawk 6212 and
PowerHawk 6312” on page 16.
The PowerHawk 6412 uses 5A secondary CTs. For instructions, see
“Installing the 5A CTs on the PowerHawk 6412” on page 19.
Current transformers connect to the PowerHawk 6212 and PowerHawk 6312
meters through the 50-conductor CT cable provided with the meter. Table 2
describes the CT wire pairs and the cable color scheme for each meter point.
You can also find this information on the inside of the meter’s outer cover.
Each CT has an X1 (positive) and X2 (neutral) wire pair and uses butt-splice
connectors to attach the CT to a specific meter wire pair. The direction of the
energy flow is indicated on the CT.
