POWER REQUIREMENTS
5.1
Verify that the Bird Dog is adequately charged before using it in the field. Refer to
reference 3.2 for details.
Note: The Bird Dog can be operated using the battery charger if the battery is low. This would require a
120volt outlet at site. If there is no 120 volt supply the Bird Dog can not be used and refer to reference
3.1 clause 10.5.1.
6.0
PORT CONNECTIONS
6.1
Verify that the voltage lead is connected properly to Port P1 on the front of the Bird
Dog.
6.2
Verify that the secondary CT lead is connected properly to Port P2 on the front of the
Bird Dog.
6.3
Verify that primary CT flex coil is connected properly to Port P3 on the front of the
Bird Dog.

Connect the three voltage leads to the test block for automatic phase rotation test. If the
Black lead is connected to the test block the Bird Dog will automatically select the phase
rotation. This step must be done as it can affect the data/vector results.
Meter Type
AutoRotation Configuration
3 Phase, 3 Wire Delta
Red lead to R (hot). White lead to W (hot). Black lead to B (hot).
3 Phase, 4 Wire Delta
Red lead to R (hot). White lead to Y (hot). Black lead to B (hot).
3 Phase, 4 Wire Wye
(2.5 Element)
Red lead to R (hot). White lead to W (neutral). Black lead to B (hot).
3 Phase, 4 Wire Wye
(3.0 Element)
Red lead to R (hot). White lead to W (neutral). Black lead to B (hot).
SETUP
8.1
Power up the Bird Dog by pressing the ON/OFF button on the front of the analyzer.
8.2
If Meter Circuit Selected is not correct Press No.
8.3
Select one of the following options for ‘Meter Circuit Types”depending on the meter
type:
Note: Use the ‘Next Item’ button to stroll through the selections. To select a meter circuit type
Press either the ABC or the CBA button depending on the circuit rotation. If the black
lead is connected to the test block it will automatically select the phase rotation regardless
of which button is selected.

Connect the voltage and secondary CT clip leads to the test block where the wires from
the CTs and PTs are terminated. Ensure that the arrow on the secondary CT clip points to
the meter side. At the CT cabinet install the primary flex coil around the bus bar,
ensuring the arrow is pointed in the direction of current flow. See the following table for
connection configurations based on Meter Type.

10.3
10.4
Select Ratio/Burden Tests from the Main Menu.
Select Wire Verify Graph, and select the phase to analyze.
Consult the vector diagrams included in this procedure to see if the results are good. If
they are not go to clause 5.7.
Record the secondary voltage on the MICS in the appropriate section. Use a voltmeter to
measure the phase-to-phase voltage at the test block and record the value.

Press EXIT and select CT Ratio/Burden Test and ensure the results are good.
Press MORE OPTN and then press GLB SAVE + STORE.
Press R+B Menu and select CT Ratio Test and phase to analyze.
Verify CT ratio is acceptable; refer to reference 3.1.Record the values on the MICS in the
appropriate section. Press STORE twice to save the data. Press EXIT.
Verify
Move probes to next phase*, refer to section 5.4.1 above for details. Go to 5.5.2.
Note: This includes the voltage leads at the test block, the secondary CT clip at the test
block and the primary flex coil at the CT.
11.0 COMPLETION
11.1
12.0
Once the commissioning is complete disconnect the Bird Dog and remove all the test
leads, voltage and current leads before neutral. Put the cabinets and test block back to
normal and seal with approved NSPI seals
TROUBLESHOOTING
12.1
If the vector diagram is not acceptable, it could be caused by one or more of the
following reasons:
-
13.0
Secondary CT clip not closed
Voltage leads not securely clamped on test switch
Leads are not measuring same phase; i.e. the voltage leads are measuring the same phase
as the current lead.
Very poor power factor, refer to reference 3.1 clause 10.5.3.
Defective wiring, refer to reference 3.1 clause 11.0
Auto Phase Rotation Test not done, see clause 5.2 of this procedure.
COMMUNICATION
13.1
13.2
13.3
13.4
Connect the Bird Dog to your PC. Make sure the serial cable is securely connected to the
port on the back of the Bird Dog.
Turn ON the Bird Dog and select UNDEFINED and then EXIT.
Select COMM.(9600)/Records and then select PC UPLOAD/RECORDS.
Select UPLOAD ALL RECORDS. A % status indicator appears on the screen and
indicates 100% when complete.
