What Makes PSI Different from Other ISPs? WT ISPa

PSI goes the extra mile to gain a comprehensive understanding of the key factors that are affecting your wind turbine component’s performance. We then use the latest diagnostic tools to detect failures. For electronics, we can uncover visibility down to the microchip level. We can even tell you about stressed components that are going to fail in the near future.

PSI Offers a Wider Range of Cost-Saving Solutions

Once we have all the pertinent performance details about your component, we share them with you so that you can make an informed decision on the best course of action. Solutions can range from minor repairs to full replacement of all printed circuit boards with upgraded designs to improve performance and reliability. In other cases, PSI can replace legacy components with newer, more reliable technology or make modification improvements to the original design. We even provide full remanufacturing services for unsalvageable, obsolete components. For example, unlike other ISPs, PSI can take a cooling plate from a blown IGBT and completely rebuild it. Service options like these allow operations and maintenance (O&M) professionals to significantly increase mean time between failures (MTBF) and prevent costly downtime and repeat repairs.
