Brendon will present on a recent project undertaken at Palmerston North Hospital that involved the establishment of a new HV supply substation, upgrades to existing HV distribution equipment and an in-situ upgrade of a clinical services LV main switchboard in the basement of the Palmerston North Hospital. The presentation will seek to provide insights into some of the more challenging aspects with upgrading infrastructure in a complex brownfield environment, and notable features implemented to reduce operational risks and ease future replacements. Aspects include: Installation challenges and delivery constraints HV and LV protection coordination with embedded generation present Maintainability and operability design factors Resiliency of supplies and closed source transfer implementation Lifecycle design factors Test approaches and integration verification DDoC's and part 1 deviation requirements Managing installation and commissioning risks Following his presentation Brendon will be available to answer questions at the end.
