The overall objective of the project is to identify an economic solution to reducing asset criticality. This will be achieved through the following activities:• Deployment of a continuous PD monitoring system at selected substations and monitoring the systems for at least 18 months to identify and understand excursions from expected levels of PD through all ambient and operational conditions• Delivery of tools for simplifying output PD data interpretation and compilation of suitable procedures for actions in event of alarms
• Review of technical confidence and effectiveness of the trial systems with other approaches to reduce asset criticality.
