Application of Symmetric Conditions in the Simulation of High Voltage Power Transmission Models

The height of the power transmitting towers is usually in the range of 10m to 40m and the separation between two consecutive towers is about 200m to 400m. In addition, the area of the ground that needs to be considered in the simulation is large. Therefore, Finite Element Method (FEM) is not suitable for simulation of this application. Whereas Boundary Element Method (BEM) is best suited for these open region problems. This paper refers to...

Q&A: Transmission Line Inspection Using Robotics

A: Hydro-Québec’s power transmission system, the most extensive in North America, covers close to 34,000 km. Similar to many power utilities, we need thorough infrastructure inspections to ensure system reliability, availability, and performance.Therefore, we have, developed robotic tools to work in places that are often hard to get to and to provide operators with diagnostic tools to assist them in their decision-making. Hydro-Québec has developed a robot, named LineScout, to inspect live transmission lines.

Q: Can you explain the robot’s applications and the benefits to customers?
