Power Recorder
Installing the Power Recorder at a Facility

4. Connect the ground current probe to the distribution system ground and
the neutral current probe to neutral, with the arrow on the current probe
pointing towards the load (away from the source) in each case.
5. Connect the remaining current probes to the power network.
• The arrow on the current probe should point toward the load.
• Use the color-coding on the leads to help you connect the probes to
the correct phases, neutral and ground.
6. Connect the remaining voltage probes.
Note
Make sure the voltage probes and current probes are paired
correctly, Phase A (L1) voltage to Phase A (L1) current and so forth.
Calculations are made in pairs and cannot be changed after data is
recorded. The leads for the voltage probe and current probe of the
same color should be attached to the same phase wire or busbar.
7. Check the LED for each phase to make sure a connection is established.
• When a phase LED is ON or lighted, you know that the connection is
active and that voltage and current is within the normal range.
• When a phase LED is BLINKING, you are connected but the voltage
or current is exceeding the normal range or exceeding the range of the
probe that you are using.
• When a current LED is OFF or unlit, there is insufficient current
present in the line.
Verifying Your Connection
Before you leave the Recorder to accumulate data at the facility, double-check
the connections.
• Make sure the current probes are secured and completely closed
around the conductors and that the voltage and current LEDs are
steady-on.
• Use the PHASOR screen on the PDA or PC to verify that the voltage
and current connections are correct. You can swap the connections
using Power View if they are incorrect.
