			Standard infrared thermography is applied to the entire substation for the purpose of locating abnormal heating of electrical equipment or components. Hot bushings, switches, and other electrical connections are detectable using this device. A thermal scan of a transformer main tank and an associated load tap changer can reveal LTC problems, blocked radiators, or bad temperature gauges. This device can be instrumental in the early detection of electrical problems. Here is a list of just a few of the problems identifiable with IR: Corroded and heating connections Lightning arresters in failure mode Load Tap Chargers in Failure mode Heating of Disonnect switches Abnormal Bus and Line Regulators Low oil levels in equipment Heating in OCB Tanks Back to the Main Page
