Scope
This document specifies the requirements for on-site infrared detection of internal overheating in gas-insulated metal-enclosed switchgear, as well as detection and diagnostic methods. This document applies to on-site infrared detection of internal overheating in SF6 gas-insulated metal-enclosed switchgear (GIS) with a rated voltage of 72.5 kV to 252 kV. The on-site infrared detection of internal overheating in SF6 gas-insulated metal-enclosed transmission lines (GIL) can be used as a reference.
