Project Overview

The International Drive (I-Drive) system in Orlando is a high-reliability distribution network designed to serve a major commercial corridor. Originally installed in 1999–2000, the system includes 13kV feeders configured into five interconnected loops. It was engineered to rapidly isolate faults on underground cables, ensuring minimal service disruption in a densely populated hospitality and retail area.

  • Creating logic diagrams and documentation to support system operation and future expansion.
  • Delivering complete as-left documentation and relay communication verification methods.
