Electrical Thermography
Using temperature patterns to screen loaded electrical connections and components.
Safety boundary: this page explains integrity concepts only. It does not provide live electrical work, pressure-equipment repair/testing, confined-space entry, radiation-source handling, machinery operation or hazardous inspection procedures.
What this topic covers
Using temperature patterns to screen loaded electrical connections and components.
Core ideas
Abnormal connection resistance can produce localized heating under load.
Comparison is most useful when load, emissivity and viewing conditions are understood.
Live electrical inspection requires qualified personnel and appropriate electrical-safety controls.
Program tradeoffs
Online observations can add value but live electrical environments create serious shock and arc-flash hazards.
What good evidence looks like
Testing methods and acceptance criteria differ by equipment and jurisdiction.
Lifecycle perspective
Condition evidence should be reviewed by qualified electrical professionals before intrusive work or operating decisions.
