SUBJECT:
Review Thermal hna in and System Maintenance Pro ram
DISCUSSION:
Last month l gave a short verbal report on the thermal imaging camera. This camera has
been very useful in our maintenance program. We use this camera during our slow months in the
winter.
We aze able to spot-check different azeas of electrical equipment (substations, riser poles,
air switches, switching cabinets and 3-phase transformers, etc.) for higher temperature
differences which indicate a connection going bad. The camera operator will take a picture of the
equipment and load it into the computer. By using the camera's sofhvaze, the operator is able to
generate a report. That report is passed onto the line department for analyzing and deterniining
how soon the problem needs to be repaired. The repair is made in the field on a scheduled time
therefore, preventing an unexpected outage which could take several hours to restore. So far, this
camera has prevented some major outages.
By using the camera more and more and attending training sessions, the operators of the
camera are getting more efficient in using it.
This program is usually done by the locators in the winter when the locate ticket numbers
are down.
I have included a few reports for your viewing.
