This paper will discuss the application of aerial thermography surveying on a transmission electrical system, and new applications involving insulator failure detection and new research in wood arm deterioration. The goal is to show the approach to an aerial survey from pre-planning the actual patrol to follow up reporting. The recent blackout of 2002 has placed more emphasis on proactive preventive maintenance programs. An identified component repair can be performed at 25% of the cost, versus a reactive unplanned approach. This excludes the loss to generators due to bottleneck flow. My analogy to this is similar to a toll hwy. When open the client is profiting when closed they are not. Hydro-One (formerly Ontario Hydro) owns, operates and maintains 30,000 km of transmission lines in a province of more than 400,000 square miles (50% bigger than the state of Texas). These 500-kV, 230-kV and 115-kV assets are valued at over $US 5B
Products & Services
Mapping and surveying services perform all of the activities that involve the physical measurement of land areas, including field surveying and data collection operations as well as the creation of maps using existing or acquired data.
Electrical insulators, high voltage bushings and porcelain insulator assemblies provide electrical isolation of power line conductors in transmission and distribution (T & D), substation, transformer, capacitor and power protection applications.
Surveying instruments are used for the accurate measurement of features, orientation and absolute positioning of large scale objects in engineering, construction, mapping, industry, defense and other applications.
Power electronics are solid state devices or transistors capable of modulating or converting electrical power.
Levels are mechanical or electronic tools that measure the inclination of a surface relative to the earth's surface.
