Installing the Power Recorder at a Facility

WCaution

Make sure the current clamps and voltage probes are paired

correctly. The leads for the current clamp and voltage probe of

the same color should be attached to the same phase wire or

busbar.

3. Connect the Recorder to the wiring by first connecting the ground probe to the

distribution system ground, and then the neutral probe to neutral.

4. With the ground clamp to the distribution system ground and the neutral clamp to

neutral connect the current clamps.

5. Connect the remaining current clamps.

• The arrow on the clamp 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 clamps are paired correctly.

Calculations are made in pairs and cannot be changed after data is

recorded. The leads for the voltage probe and current clamp 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 clamps 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 to verify that the voltage and current

connections are correct. You can swap the connections using Power View if they

are incorrect.

Finishing UP

After making any corrections to the connections, recheck the PHASOR diagrams to

confirm your connection. Make sure the nominal voltage, nominal line frequency, and

power type (delta, wye, other) are correct before you leave the Recorder. It is a good

practice to insert a Start Mark when you are finished with all settings so you can

download data and ignore useless readings and events common at the beginning probe

connecting activities.
