Thermographic survey

A loose connection heats up long before it fails, and an annual scan has a one in twelve chance of being in the right month. Sensors on the boards that matter watch every day.

What does a thermographic survey involve?

Thermographic survey checks: temperature rise over ambient and over the adjacent phase at each connection, under recorded load. Observed by thermal imaging camera under load; wireless temperature sensors on critical terminations. The interval: a monitored condition can replace the fixed interval.

asset class
Condition that replaces the interval
Connection temperature above ambient by 10 C (investigate) or 35 C (act), or above the adjacent phase by 10 C; continuous temperature sensing on busbars and terminations replaces the periodic scan on critical boards
Reading that proves it
Temperature rise over ambient and over the adjacent phase at each connection, under recorded load
Evidence an auditor accepts
Survey report per board with images, load at the time and the temperature rise per finding, and the repair record
First move
Scan under at least 40% load and record the load; a scan on a lightly loaded board proves nothing.
