G0003 - 5 - Glow Wire Thermocouple

Product details

The Glow Wire Thermocouple allows for a test to be carried out assessing the effects of 

heat generated by electrical faults and overloads within electrical equipment in solid insulated 

materials and non-metallic enclosures containing or supporting current carrying parts with 

regard to ignitability and propagation of flame.

An electrically heated small loop of resistance wire “Glow-wire" is applied to those insulation 

surfaces likely to be subjected to heat generated by fault conditions or overloads. The 

temperature and duration of application of the glow-wire is dependant upon the operational 

ａnd service conditions of the equipment under test. The glow-wire thermocouple is an integral 

part of this test.

The glow wire must be introduced at right angles to the test specimen with a force of 0.8 

to 1.2N and the glow-wire and test specimen must be moved towards each other over a 

distance of up to 7mm.
