As many Nova Scotia Power customers around metro Halifax and elsewhere gazed out their windows at the relatively calm weather conditions late this morning, they may have wondered why they were in the dark. Are the transmission lines held with bubble gum? Transmission lines are high-voltage connectors that run along highways and carry electricity from the power plants, while distribution lines, which have a lower voltage, branch off from those transmission lines and bring power directly to customers. So when New Brunswick Power experienced a transmission interruption in Memramcook, the system there tried to draw power from Nova Scotia's. But since Nova Scotia didn't have enough power, those protective measures came into effect and created outages on both sides.
