Con Edison Projects - Secondary Events

Our goal is to rank the electricity service structures (manholes and service boxes) in Manhattan, Brooklyn, Bronx, and Queens according to their vulnerability to serious manhole events such as manhole fires, explosions and smoking manholes. Our data includes Con Edison ECS (Emergency Control System) trouble tickets, which are records of past events affecting the secondary (low voltage) electric distribution system such as a manhole fire, manhole explosion, smoking manhole, no-light event, low voltage event, flickering light event, side-out partial outage, or burnout. The overall goal of our system is to assist Con Edison to prioritize the inspection of manholes and service boxes in four boroughs and to prioritize long-term follow-up repair works.
