- Procedure
- 1. Remove the control voltage and AC signals from the 825-P by opening the appropriate breakers or removing fuses.
- 2. Isolate the relay trip contact.
- 3. Verify the correct AC and DC connections by performing point-to-point continuity checks on the associated circuits.
- 4. Apply AC or DC control voltage to the relay.
- 5. After the relay is energized, the front panel green ENABLE LED illuminates.
- 6. Connect a PC to the relay using an appropriate serial cable.
- 7. Start the MPS Explorer software and establish communication with the relay.
- 8. Set the correct relay time and date using either the front panel or MPS Explorer software.
- 9. Enter the relay settings for your application.
- 10. If you are connecting an external RTD scanner, follow the substeps below; otherwise continue with Step 11.
- 11. Verify the relay AC connections.
- 12. Connect the AC test source current or voltage transformers to the relay side of the open breaker or contactor.
- 13. Apply the rated current.

- 4. Apply the appropriate magnitude for each phase current as shown in column 1 of Table 86
- Power and Power Factor Measuring Accuracy
- Wye-Connected Voltages
- 1. Connect the current source to the MCM module, as shown in Figure 50.
- 2. Connect the voltage source to the 825-P, as shown in Figure 51. Make sure that Xfmt Connection = Wye.
- 3. Using the front panel SET/SHOW or MPS Explorer software, record the Phase CT Ratio, Phase VT Ratio, and Phase Rotation setting values.
- 4. Apply the current and voltage quantities shown in Column 1 of Table 87. Values are given for Phase Rotation = ABC and Phase Rotation = ACB.
- 5. Use the front panel METER function or MPS Explorer software to verify the results.
- Delta-Connected Voltages
- 1. Connect the current source to the MCM module, as shown in Figure 50 on page 151.
- 2. Connect the voltage source to the 825-P, as shown in Figure 52. Make sure that Xfmr Connection=Delta.
- 3. Use the front panel SET/SHOW or MPS Explorer software to record the Phase CT Ratio, Phase VT Ratio, and Phase Rotation setting values.
- 4. Apply the current and voltage quantities shown in Column 1 of Table 88. Values are given for Phase Rotation = ABC and Phase Rotation = ACB.
- 5. Use the front panel METER or MPS Explorer software to verify the results.
