What is the purpose of testing all phases during the IVV stages?

Testing all phases during the Installation, Verification, and Validation (IVV) stages is crucial to ensure that all phases of the system are functioning correctly. This phase of testing verifies that each individual phase operates as intended, contributing to the overall performance and reliability of the system. Ensuring functionality in all phases means that the system can deliver the required power and performance without interruptions or imbalances that could lead to operational issues.

Additionally, testing all phases allows for the identification of potential problems with individual phases, which can affect the system's efficiency and safety. It helps to determine that there are no discrepancies in the phase outputs, which is essential in applications where balanced loads are critical for optimal performance.

While confirming grounding, checking high voltage capability, and ensuring uniform voltage are important in various contexts, the primary focus during IVV stages is on the functional integrity of each phase to ensure a robust and reliable system.
