or on any piece of electrical component is ionized due to a high electrical
field thereby creating CORONA and or ARCING. Click

CORONA-activity creates corrosive substances, like nitrogen oxides and ozone. These degrade the polymer housing and any electrical component. This allows moisture and acid to penetrate the fiberglass rod, leading to insulator or component failure. A fault on a polymer insulator usually progresses rapidly and may lead to line failure.
The ability to easily detect corona and arcing sources and pinpoint their locations can save utility companies considerable money. Aerial UV scans, when coupled with an aerial platform, increases the reliability of our customers' systems. You can now access areas that could not normally be inspected by ground methods, thus allowing for better preventative maintenance, less downtime, and increased reliability.
The information collected allows managers to schedule maintenance and avoid electrical components failures as well as unforeseen safety issues.
