Fault Rotate
Fault rotate assumes that the relay under test is three-phase, or a system
of three single-phase relays. Ensure relay connections for current sources
I2 and I3, and for logic input 1.
The Fault Rotate feature on the Control Panel allows a fault to be
rotated from one phase to the next. Use a current relay with a tap value
of 5 A and set the fault current in source I1 at 10 A. See the source table
in Figure 5.15 on page 5-18.
To rotate this fault through all three phases, follow these steps:
1. Click Tools|F6000 Configuration in the ProTesT menu bar.
The Configuration display appears (Figure 5.1 on page 5-2).
2. Select 3 Voltages and 3 Currents from the Pre-set Configurations pick
list.
3. Click OK to apply the configuration to the instrument and close the
display.
The Control Panel is again the active window.
4. In the source table, increase the range for current sources I1, I2, and
I3 from 7.5 A to 15 A.
5. Verify that the Fault Rotate button in the phasor diagram is active.
If the Fault Rotate button is grayed out, verify that 3 Voltages and
3 Currents is the selected source configuration. Also verify that all
three voltage sources have a range of 75 V, and all three current
sources have a range of 15 A.
For this example the voltage sources are not required.
