Answer / Mohammad Arman Ansari

{"Procedure": "The NPS (Negative Phase Sequence Test) is performed to check the equipment's response to negative phase sequence voltages. Here are the general steps:
1. Disconnect all loads from the equipment.
2. Connect a voltage source capable of producing negative sequence voltages.
3. Measure the current flowing through the equipment during the test.
4. Analyze the results to determine any issues or imbalances in the equipment's operation under negative phase sequence conditions."}
