Enphase Solar Energy Private Limited engaged NV Dynamics to conduct a failure analysis on the light pipe of a microgrid interconnection equipment: IQ System Controller RoW. This involved two specific operations on the equipment panel:
Drilling at specified openings using a hole saw tool with the drill machine operating at maximum speed (both on a bench and on a wall)
Conducting wall drilling operations using a long concrete bit through the equipment panel.
In this current undertaking, a pair of tri-axial vibration transducers were employed. One was positioned in close proximity to the light pipe, while the other was securely mounted atop using an aluminum block. Both transducers were subsequently integrated into a unified multi-channel data acquisition system. Vibration trials were conducted for various test conditions.
Following data processing and in-depth analysis, practical recommendations were provided to the client, derived from the acquired results.
