Transmission lines are the critical backbone of the utility power grid. They are the “heavy lifters” of electricity, providing the link between electrical generation plants and substations that distribute power to the consumer. Power outages on these lines can be widespread affecting from several hundred to thousands of customers. Typical thermal problems occurring on such lines include loose connectors and splices. Equally to blame are failed insulators which are the result of damage due to corona discharge.
This presentation is based on a recent project that used solar-blind UV cameras and infrared thermal imagers to inspect a large transect of 138kV transmission lines in Florida. The results of this study will look at the common factors these technologies share and point out their unique strengths for inspecting transmission lines. Also presented is how drones were used to document and classify the severity of reported problems.
Infrared inspections of electrical systems often include high visibility equipment such as substations, switchgear and motor controllers. In this Tip we discuss several critical items that are often overlooked during infrared inspections.
Burlington, NJ January 30, 2019 — Infraspection Institute’s IR/INFO Conference was held earlier this month in New Orleans, LA. IR/INFO 2019 marks the 30th anniversary for the advanced training conference, technical symposium and technology expo.
