That raises another difference between Hydro One and Hydro Ottawa: Hydro Ottawa has sensors on primary all over the network (something like every 3-5 km). The sensors make it possible to locate faults within a fairly small part of the distribution network almost instantaneously. In contrast Hydro One has very few sensors, maybe one every 15 to 20 km in parts of the network, and sometimes no sensors at all on rural lines that can require driving 50+ km of line to find the fault. We routinely have 4-6 hour power outages, and a good chunk of the repair time is spent finding the fault. Again, Hydro One could install more reclosers on rural lines to isolate faults, but that doesn't seem to be the design philosophy they follow. It's not entirely Hydro One's fault. Building a sensor network in rural Canadian shield geography is challenging as getting radio signals through rocks, hills and trees can be almost impossible, but I still think they can do better.
