Scope

This document describes the method of using terahertz detection technology to detect insulating materials used in electrical equipment.
This document is applicable to the detection of defects and moisture content in solid insulating materials with a thickness of 0.03 mm to 10 mm, as well as the moisture content of liquid insulating materials. Solid insulating materials with other thicknesses should be referenced for implementation.
This document is not applicable to cellulose-based solid insulating materials with a thickness exceeding 5 mm.
