Project Challenges

  • Obtaining sufficient information to conduct the discrimination protection study.
  • Adapting quickly when project details change, for example panel model numbers and ratings.
  • Level of detail required by Jemena, for example disconnection time of diesel automatic transfer switches.
  • Scheduling commissioning of grid protection relay as soon as it is ready
